CICS returns 500 and we may have the wrong adapter

A generated CICS service returns 500. Someone suggested swapping the Docker tag. What should we check?

Match the adapter to the CICS interface you are actually calling, not to a nearby image name. IMS, DB2, and CICS are different connectors. A 500 after deploy is often the wrong communication path or a host error, not a license problem. Collect the connector type, the host error, and the Hub project before we change tags.
