Seeing events, but processing 0 indicators

[MReprogle1]

I am hoping to figure out what is breaking in this process, but I recently set up MISP and we were even successfully able to send about 30 events to Sentinel as of 09/04/24. However, when I try to manually push events, it seems to be seeing the events, but throws the 'Unexpected properties for Identity' error (which shows me that it is in fact able to log into MISP via the API key.. However, it seems to not process anything and sends nothing.

I even check the Enterprise app side of things, and I am actually seeing log successful service principal logins, so it does seem to still connect to the enterprise app with no issue:

We currently have a self-signed certificate to enable SSO to work on the server, but I have "misp_verifycert = False" in config.py. We did set this SSO up last week, and this is the only thing I can think of that might break anything, but I find it strange that it seems to be getting to MISP fine, and even goes out to the Enterprise App fine, but just doesn't seem to process anything to send in the first place.
