on 8th april out of 1 million request we started getting 30k errors from microsoft graph client error com.microsoft.graph.http.GraphServiceException: Error code: InvalidAuthenticationToken Error message: Unable to initialize RPS
This was all sudden, Can anyone help with root cause ? We did not make any changes in the code and we are using 2.8.0 version for this client sdk library

Christos Georgiou 21 Reputation points2021-04-21T11:26:33.06+00:00 We've also been hit with this; it seems to be connected to specific OneDrive personal accounts rather than being a spurious response. This happens right after we POST to the auth /token/ endpoint and receive a typically functional Bearer access token; we then proceed to use said access token GETting the /me/ endpoint. For some people the just-generated access token can't be used and the following is returned:
{"error": {"code": "InvalidAuthenticationToken", "message": "Unable to initialize RPS", "innerError": {"date": 2021-04-21T10:57:53", "request-id": "eac46e10-680a-4787-8c56-757c481686be", "client-request-id": "eac46e10-680a-4787-8c56-757c481686be"}}I provide the example with real request-id and date because maybe it helps someone at MS to pinpoint the issue.
