{panel:title=Identity Error Response to DBaaS Control Plane}
2022-09-26 11:35:06,117 ERROR [dw-23361 – POST /20160918/externaldatabaseconnecto] [opc-request-id=csid4c3657b9498b921a01034931775d/1468ac8d7e80467aba11b99d108b0cde/FB705FE0BFC4FD0561439CA8414BE27D] c.o.p.c.e.s.CatchAllExceptionMapper: Uncaught exception.

{panel}

The following two tags were the reason for tag validation failure:
{panel}
‘oracle-tags”cognizant-oci’
{panel}

SOLUTION

For OCI user, adding this database to OCI External Database Management service, need to add a policy authorizing updates to tag-namespaces
