While creating a Knowledge Assistant in Databricks, I encountered an issue where the endpoint update failed with the following message:

"Failed to deploy: served entity creation aborted because the endpoint update timed out. Please see service logs for more information."

The endpoint status shows Not Ready (Update failed), and the service logs contain:

Steps tried:

  • Verified the base model (ka-base-model)

  • Attempted multiple endpoint updates

  • Retried after some time – same error persists

Has anyone faced a similar issue with Knowledge Assistant endpoint deployment? How can I resolve the credential error?

Hi @sathyavikasini ,

Are you still facing this issue? While creating the agent, do you see that your configured knowledge sources are processing?

If you haven't done so already, you might check permissions on the catalog/schema/volume(s) that are configured as knowledge sources. Also, the 401 credential errors have occurred with other workloads when account admins enable admin isolation flags, so that's another thing to check if you're still running into the timeout error.
