Also noticed this when accidentally running the standard connector against IBM Data Engine.
Again, only an internal server error with no other information logged.
Enabling debug showed the issue was a missing thrift library, but crucially this error never surfaced to the audit log or user

When testing the HMS connector I an issue which did not result in any Audit log entries:
Class loading error
Due to a build error, I had a problem with the connector hitting a class loader exception when issuing
The error was in trying to load from javax.xml
Whilst the build error (during refactoring) is fixed, this exception results in an 'Internal server error' and no output on the audit log.
It's possible other similar circumstances could cause an issue
