This was verified for Session Creation Requests with duplicate URR Ids, but likely applies to other IEs and to Session Modification Requests, too

Duplicate PDR/FAR/URR Ids in PFCP Session Establishment Request are IMHO not permitted. And I'm quite sure that erGW is not generating such requests.

How did you come by those requests?

I made a mistake in an E2E test case and noticed that issue (request succeeded despite duplicate IDs). As indeed ergw doesn't generate such requests, the problem is not critical but nevertheless worth fixing at some point. Such requests need to be rejected.
