CRASH.05 CX_NWBC=>INVALID_COMMAND

Symptom

An unknown command has been specified in the URL.

Solution

Specifically if this exception is raised on the startup URL (as used by NWBC for Desktop) of /sap/bc/nwbc/TicketIssuer, this is a clear indicator that the ABAP system only has a beta version of the NWBC runtime that is not officially supported.

Update the service pack level to a minimum level supported.
