D365 data connection produces Obeject Reference Errors

[tonykiefer]

D365 data connection produces Obeject Reference Errors combobox and dropdown where the same data controls produced no error when connected to SQL on prem db.

So I'm getting a lot of these errors on most of my controls.  Previously when the data connection was to an on prem SQL db I had no errors.  Now that I'm connected to D365 I get the errors.

Important note...that application runs, the data populates all controls, parent.default records populate, new and edited data saves!  How can I correct the errors?  And why would I have to add validation with D365 data when I didn't need to do it with SQL?

@RandyHayes...If you have time can you take a peak at this?  I examined the console and I initially get status of 200 then all the control throw 400 errors.  Note:  All CRUD operations are working but these errors persist only on Comboboxes!

I opened a helpdesk ticket through Microsoft and they determined this is a throttling issue.  There are some settings in D365 F&O to help resolve this case.
