#2605 [Core feature] Improved and detailed error messages on JWT validation failures Issue created by katrogan Motivation: Why do you think this is important? When flyteadmin fails JWT token validation, the request fails with

Unauthenticated desc = token parse error [JWT_VERIFICATION_FAILED] Could not retrieve id token from metadata, caused by: rpc error: code = Unauthenticated desc = Request unauthenticated with IDToken

but this is ambiguous. For example, if the audience is misconfigured, flyteadmin logs

"Failed to parse Access Token from context. Will attempt to find IDToken. Error: invalid audience

which is far more useful for understanding misconfigured deployments and diagnosing what went wrong Goal: What should the final outcome look like, ideally? Flyteadmin auth failures should include more details in error message responses Describe alternatives you've considered N/A Propose: Link/Inline OR Additional context No response Are you sure this issue hasn't been raised already? ☑︎ Yes Have you read the Code of Conduct? ☑︎ Yes flyteorg/flyte
