Managed resource ownership validation is unavailable.

Error message

Managed resource ownership validation is unavailable.

What it means

HTTPException(500) in managed-resource ownership validation: require_managed_files is enabled and a unified resource id was supplied, but the managed_files hook object is not a ManagedResourceAccessChecker instance — the ownership check infrastructure is missing/incompatible, so validation cannot proceed safely.
