v1.7.8 Known issues

This release has the following known issues, listed by component and area.

v1.7.8 Known issues: Tanzu Application Platform

The Tanzu Application Platform integration with Tanzu Service Mesh does not work on vSphere with TKR v1.26. For more information about this integration, see Set up Tanzu Service Mesh. As a workaround, you can apply the label to update pod security on a TKr v1.26 Kubernetes namespace as advised by the release notes for TKr 1.26.5 for vSphere 8.x. However, applying this label provides more than the minimum necessary privilege to the resources in developer namespaces.

v1.7.8 Known issues: API Auto Registration

Registering conflicting groupId and version with API portal:

If you create two CuratedAPIDescriptors with the same groupId and version combination, both reconcile without throwing an error, and the /openapi?groupId&version endpoint returns both specifications. If you are adding both specifications to the API portal, only one of them might show up in the API portal UI with a warning indicating that there is a conflict. If you add the route provider annotation for both of the CuratedAPIDescriptors to use Spring Cloud Gateway, the generated API specspecification includes API routes from both CuratedAPIDescriptors.

You can see the groupId and version information from all CuratedAPIDescriptors by running:
```
$ kubectl get curatedapidescriptors -A

NAMESPACE           NAME         GROUPID            VERSION   STATUS   CURATED API SPEC URL
my-apps             petstore     test-api-group     1.2.3     Ready    http://AAR-CONTROLLER-FQDN/openapi/my-apps/petstore
default             mystery      test-api-group     1.2.3     Ready    http://AAR-CONTROLLER-FQDN/openapi/default/mystery
```
When creating an APIDescriptor with different apiSpec.url and server.url, the controller incorrectly uses the API spec URL as the server URL. To avoid this issue, use server.url only.

v1.7.8 Known issues: Application Live View

On the Run profile, Application Live View fails to reconcile if you use a non-default cluster issuer while installing through Tanzu Mission Control.

v1.7.8 Known issues: Artifact Metadata Repository Observer and CloudEvent Handler

Periodic reconciliation or restarting of the AMR Observer causes reattempted posting of ImageVulnerabilityScan results. There is an error on duplicate submission of identical ImageVulnerabilityScans you can ignore if the previous submission was successful.

v1.7.8 Known issues: Bitnami Services

If you try to configure private registry integration for the Bitnami services after having already created a claim for one or more of the Bitnami services using the default configuration, the updated private registry configuration does not appear to take effect. This is due to caching behavior in the system which is not accounted for during configuration updates. For a workaround, see Troubleshoot Bitnami Services.

v1.7.8 Known issues: Cartographer Conventions

While processing workloads with large SBOMs, the Cartographer Convention controller manager pod can fail with the status CrashLoopBackOff or OOMKilled. For information about how to increase the memory limit for both the convention server and webhook servers, including app-live-view-conventions, spring-boot-webhook, and developer-conventions/webhook, see Troubleshoot Cartographer Conventions.

v1.7.8 Known issues: Contour

A renewed CA certificate might not get updated in the CA section of Envoy and Contour certificate’s secrets

v1.7.8 Known issues: Crossplane

The Crossplane validatingwebhookconfiguration is not removed when you uninstall the Crossplane package. To workaround, delete the validatingwebhookconfiguration manually by running kubectl delete validatingwebhookconfiguration crossplane.

v1.7.8 Known issues: Service Bindings

When upgrading Tanzu Application Platform, pods are recreated for all workloads with service bindings. This is because workloads and pods that use service bindings are being updated to new service binding volumes. This happens automatically and will not affect subsequent upgrades.

Affected pods are updated concurrently. To avoid failures, you must have sufficient Kubernetes resources in your clusters to support the pod rollout.
ServiceBinding is not immediately reconciled when status.binding.name changes on a previously bound service resource. This impacts the timely rollout of new connection secrets to workloads. The reconciler eventually picks up the change but this might take up to 10 hours. As a temporary workaround, you can do one of the following:
- Delete the existing ServiceBinding and create a new one that is identical.
- Trigger reconciliation of the existing ServiceBinding by adding an arbitrary annotation or label.
- Delete and recreate the application workload referred to by the ServiceBinding.

v1.7.8 Known issues: Services Toolkit

An error occurs if additionalProperties is true in a CompositeResourceDefinition. For more information and a workaround, see Troubleshoot Services Toolkit.

v1.7.8 Known issues: Supply Chain Choreographer

By default, Server Workload Carvel packages generated by the Carvel package supply chains no longer contain OpenAPIv3 descriptions of their parameters. These descriptions were omitted to keep the size of the Carvel Package definition under 4 KB, which is the size limit for the string output of a Tekton Task. For information about these parameters, see Carvel Package Supply Chains.
When using the Carvel Package Supply Chains, if the operator updates the parameter carvel_package.name_suffix, existing workloads incorrectly output a Carvel package to the GitOps repository that uses the old value of carvel_package.name_suffix. You can ignore or delete this package.
If the size of the resulting OpenAPIv3 specification exceeds a certain size, approximately 3 KB, the Supply Chain does not function. If you use the default Carvel package parameters, this issue does not occur. If you use custom Carvel package parameters, you might encounter this size limit. If you exceed the size limit, you can either deactivate this feature, or use a workaround. The workaround requires enabling a Tekton feature flag. For more information, see the Tekton documentation.
Supply Chains that use SSH auth with the git-writer resource will fail in the gitops step. As a workaround, use HTTPS auth.

v1.7.8 Known issues: Supply Chain Security Tools - Policy

Supply Chain Security Tools - Policy is defaulting to TUF enabled due to incorrect logic. This might cause the package to not reconcile correctly if the default TUF mirrors are not reachable. To work around this, explicitly configure policy controller in the tap-values.yaml file to enable TUF:
```
policy:
  tuf_enabled: true
```

v1.7.8 Known issues: Supply Chain Security Tools (SCST) - Scan

When using SCST - Scan 2.0 with a ClusterImageTemplate, the value for the scanning image is overwritten with an incorrect default value from ootb_supply_chain_testing_scanning.image_scanner_cli in the tap-values.yaml file. You can prevent this by setting the value in your tap-values.yaml file to the correct image. For example, for the Trivy image packaged with Tanzu Application Platform:
```
ootb_supply_chain_testing_scanning:
  image_scanner_template_name: image-vulnerability-scan-trivy
  image_scanning_cli:
    image: registry.example.com/tanzu-application-platform/tap-packages@sha256:675673a6d495d6f6a688497b754cee304960d9ad56e194cf4f4ea6ab53ca71d6
```
When using SCST - Scan 2.0, Trivy must be pinned to v0.42.1. This is because CycloneDX v1.5 is the default for later versions of Trivy and is not supported by AMR.
The Snyk scanner outputs an incorrectly created date, resulting in an invalid date. If the workload is in a failed state due to an invalid date, wait approximately 10 hours and the workload automatically goes into the ready state. For more information, see this issue in the Snyk GitHub repository.
SCST - Scan 1.0 fails with the error secrets 'store-ca-cert' not found during deployment by using Tanzu Mission Control with a non-default issuer. For how to work around this issue, see Deployment failure with non-default issuer.

v1.7.8 Known issues: Supply Chain Security Tools - Store

AMR-specific steps have been added to the Multicluster setup for Supply Chain Security Tools - Store.
SCST - Store automatically detects PostgreSQL database index corruptions. If SCST - Store finds a PostgresSQL database index corruption issue, it does not reconcile. For how to fix this issue, see Fix Postgres Database Index Corruption.
When observer.deploy_through_tmc is true, properties are auto-configured for Tanzu Mission Control (TMC). This causes the MultiClusterPropertyCollector resource to overwrite existing Tanzu Application Platform values for Observer.

When using Let’s Encrypt ACME issuers, the resultant Kubernetes secret resource does not contain a ca.crt property. Therefore, when the MultiClusterPropertyCollector resource creates the Observer package configuration values secret, the required ca_cert_data is empty.

To work around this issue, add the Certificate Authority (CA) Certificate to the shared.ca_cert_data key in the Tanzu Application Platform installation values.

v1.7.8 Known issues: Tanzu Build Service

During upgrades a large number of builds might be created due to buildpack and stack updates. Some of these builds might fail due to transient network issues, causing the workload to be in an unhealthy state. This resolves itself on subsequent builds after a code change and does not affect the running application.

If you do not want to wait for subsequent builds to run, you can manually trigger a build. For instructions, see Troubleshooting.

v1.7.8 Known issues: Tanzu Developer Portal

If you do not configure any authentication providers, and do not allow guest access, the following message appears when loading Tanzu Developer Portal in a browser:
```
No configured authentication providers. Please configure at least one.
```
To resolve this issue, see Troubleshooting.
When viewing a supply chain with the Supply Chain Choreographer plug-in, scrolling horizontally does not work. Click and drag left or right instead to move the supply chain diagram. A fix is planned for the future. The zoom function was removed because of user feedback.
Ad-blocking browser extensions and standalone ad-blocking software can interfere with telemetry collection within the VMware Customer Experience Improvement Program and restrict access to all or parts of Tanzu Developer Portal. For more information, see Troubleshooting.
ScmAuth is a Backstage concept that abstracts Source Code Management (SCM) authentication into a package. An oversight in a recent code-base migration led to the accidental exclusion of custom ScmAuth functions. This exclusion affected some client operations, such as using Application Accelerators to create Git repositories on behalf of users.
The back-end Kubernetes plug-in reports failure in multicluster environments. In a multicluster environment when one request to a Kubernetes cluster fails, backstage-kubernetes-backend reports a failure to the front end. This is a known issue with upstream Backstage and it applies to all released versions of Tanzu Developer Portal. For more information, see this Backstage code in GitHub. This behavior arises from the API at the Backstage level. There are currently no known workarounds. There are plans for upstream commits to Backstage to resolve this issue.

v1.7.8 Known issues: Tanzu Developer Tools for IntelliJ

The error com.vdurmont.semver4j.SemverException: Invalid version (no major version) is shown in the error logs when attempting to perform a workload action before installing the Tanzu CLI apps plug-in.
If you restart your computer while running Live Update without terminating the Tilt process beforehand, there is a lock that incorrectly shows that Live Update is still running and prevents it from starting again. For the fix, see Troubleshooting.
Workload actions and Live Update do not work when in a project with spaces in its name, such as my app, or in its path, such as C:\Users\My User\my-app. For more information, see Troubleshooting.
An EDT Thread Exception error is logged or reported as a notification with a message similar to "com.intellij.diagnostic.PluginException: 2007 ms to call on EDT TanzuApplyAction#update@ProjectViewPopup". For more information, see Troubleshooting.

v1.7.8 Known issues: Tanzu Developer Tools for Visual Studio

Clicking the red square Stop button in the Visual Studio top toolbar can cause a workload to fail. For more information, see Troubleshooting.
