HTTP Error 400 - Bad request, Ivalid URL with D365 Fin&Ops connection

Hi all,


I have created a very simple powerapp (generated PowerApps from data) and connected to D365 Fin&Ops. I'd like to edit a value on a simple form in the existing record. When I submit the form I receive an error message: Bad request - Invalid URL, HTTP error 400, the request URL is invalid.





All the other tables I can edit, change, and add new record.


Any ideas about this problem?
