Error when submitting to SharePoint

[TicaAppBuilder]

Building my first "real" PowerApp to a SharePoint site. My test app does not have this error, I built in a similar way from a different SharePoint site. 

The error is as follows:

"message": "The data returned from the tagging UI was not formatted correctly\r\nclientRequestId: 7751f9da-25b5-44b8-b20d-3eaebf029ea3\r\nserviceRequestId: 7751f9da-25b5-44b8-b20d-3eaebf029ea3"

Any ideas? Thanks!

In case it helps, here's a screenshot of the entire error screen:

I figured out what was happening - there was a field that I was not using on the screen that I was submitting and it was required. It was "inherited" from the SharePoint site, so I made it not required in the SP site, and then was able to submit without the error. 

Hope it helps someone! 🙂
