Code with PUT request of "https://graph.microsoft.com/beta/external/connections/" was working somedays ago fine and now throwing error:
"{ "error": { "code": "BadRequest", "message": "Property content in payload has a value that does not match schema.", "innerError": { "request-id": "a823ed79-63a2-4512-864e-acdd15e523f7", "date": "2020-04-17T03:01:01" } } }"
Tried to execute request in C# dotnet console application, Graph Explorer, Postman and receive same error across
Graph Explorer screenshots below:

Any suggestions on how to resolve this error? Can there be any changes to beta release without proper documentation?
