ServiceNow Yokohama Integration with vRealize Automation Fails with Error casname not found

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

When attempting to execute vRealize Automation (vRA) provisioning workflows directly from a ServiceNow Yokohama instance running the 9.0.2 plug-in, requests fail to submit to the vRA endpoint. The operation throws the following explicit error string in the ServiceNow execution logs:
casname not found

This deployment failure blocks all downstream automation flows and catalog requests initiated from the ServiceNow User Interface.

 

Environment

VMware Aria Automation 8.18

Cause

The issue is caused by configuration corruption and orphaned workflow references within the local ServiceNow update tables. This occurs when a malformed or incomplete development update set is applied over the active workflow, which misses critical dependencies and delinks the running workflow instance from the official store version database layout.

Resolution

To resolve this issue, you must purge the corrupted application remnants and establish a clean re-installation. Follow these steps:

1. Remove Broken Endpoint Mappings: Navigate to your ServiceNow integration settings, delete the existing vRA endpoint connection, and clear out any associated credential mappings.

2. Uninstall the Application: Completely uninstall the vRA 9.0.2 plug-in application from the ServiceNow instance.

3. Purge Residual Artifacts: Perform an explicit database cleanup to remove orphaned workflow links and remnants by following the steps outlined in the canonical ServiceNow platform document ServiceNow KB1218443.

4. Reinstall and Reconfigure: Reinstall a clean copy of the 9.0.2 plug-in application from the store, recreate the vRA endpoint, and re-verify workflow submission functionality.
