There was a problem adding your data source. Please try again

A bit of an unclear message and the try again isn’t going to help either.

KeyColumn

When looking at the details of the error things became a bit clearer:

Session ID: b6b3017a-1ae5-a4ac-2af3-3f36837e68b6

I added a primary key to my table and the problem disappeared and I was able to add my data source.
