registerClient threw OmmInvalidUsageExceptionImpl

I observed this error once on startup when loading 410746 subscriptions, and it did not occur again re-running the same code and RIC set, so it is intermittent and rare. What would be the best way to handle these? (and is this a bug on the refinitiv server side?)

I don't see any sign of disconnect. There is nothing else in the logs and the next call to registerClient worked.
