we are seeing more and more NumberFormatException issues with one of our resources (MS Graph Connector - which I know is not supported, but I'm not sure this is a connector issue). It looks like it is trying to format the uid to a numeric value - which is strange.
I've added an anonymised excerpt from the log. This is causing a few problems in our operational running now.
Let me know if you need additional logs. I hope it's not a misconfiguration on my part.
