All my reports (largely connected to Dataverse) will no longer refresh and display the below message.
Hi, DonalMc
I had the same issue. I'm using a parameter as the URL for the database, which I named 'environment-url'. Everything worked perfectly at first, but then an error started to appear. I had to rename it to 'environmentUrl', and the error disappeared.
I'm not sure if it helps you but I was able to solve it for my case.
