Error with CRUD pages

I was able to get CRUD working after this latest update. However, save is broken with a generic error (which shows up twice):
Post (server) with arguments () - ModelState is Invalid

I cannot find where this discrepancy is and this doesn't tell me which field it thinks is wrong.

Thanks

Can you check the exception in thе network tab of your browser developer tools?

It is a 404, from what this says:
