To workaround this issue in VMware Cloud Foundation :
- Find the failed workflow ID in the SDDC Manager UI.
- Expand the failed Workflow in the Tasks list and then click on the View Subtasks link.
- Find the workflow ID in the browser URL. There will be something similar to: (monitoring-panel:monitoring/tasks/subtasks/c6db71f0-XXXX-XXXX-XXXX-93b7cda0e148). c6db71f0-XXXX-XXXX-XXXX-93b7cda0e148 is the Workflow ID.
- Log in to the SDDC Manager VM as the vcf user and then issue su - to switch to the root user.
- Issue a command similar to the following to delete the failed Workflow:
curl -X DELETE http://localhost/tasks/registrations/c6db71f0-XXXX-XXXX-XXXX-93b7cda0e148
Note: Replace c6db71f0-XXXX-XXXX-XXXX-93b7cda0e148 with the Workflow ID value obtained in Step 1b.
