Troubleshooting failed workflow runs

If your workflow subscription fails, you can perform troubleshooting steps to correct it.

When a workflow run fails you might receive an error message, a failed status, and a failed log. If your workflow run fails, it can be a result of several common problems.

Problem	Cause	Solution
Your vRealize Orchestrator workflow subscription did not start or complete successfully.	You configured a workflow subscription to run a custom workflow when the event message is received, but the workflow does not run or complete successfully.	Verify that the workflow subscription is saved correctly. Verify that the workflow subscription conditions are configured correctly. Verify that the workflow is configured correctly within vRealize Orchestrator. Verify that the vRealize Orchestrator has the specified workflow.
Your vRealize Orchestrator workflow did not run for an approval request.	You configured a pre-approval or post-approval workflow subscription to run a vRealize Orchestrator workflow. The workflow does not run when a machine that matches the defined criteria is requested in the service catalog.	To successfully run a workflow subscription for an approval, you must ensure that all the components are configured correctly. Verify that the approval policy is active and correctly applied. Verify that your workflow subscription is correctly configured and saved. Review the event logs for messages related to approvals.
Your approval request was rejected.	You configured a pre-approval or post-approval workflow subscription that runs the specified vRealize Orchestrator workflow, but the request is unexpectedly rejected. All the approval levels before this external approval level were approved, and this level should have been approved, but was processed as rejected. One possible cause is an internal error when vRealize Orchestrator tried to run the workflow. For example, the workflow is missing or the vRealize Orchestrator server is not running.	Review the logs for messages related to approvals.
