Hi @nmathewa thank you for the report! I think this is related with #23529 From #23529 (comment) seems like the error is harmless and a fix will be done in a future release.

Let us know if the info above helps!

Thanks @dalthviz .

Changing status to Closed as it appears to be a duplicate of issue #23529.
