Hello and thank you very much for your interest.
I confirm that I have already tried with postman to verify the API and I get a positive response.
Furthermore, from PowerBI I tried to connect via WEB to the address and by entering the credentials I was able to log in successfully.

Hi @alops1 ,

"500: Internal Server Error" is mostly the server encountered an unexpected condition that prevented it from fulfilling the request.
There are several possible scenarios that can lead to this error. I suggest that you first test the availability of the API directly to make sure the headers information is correct. It may be that some of your headers are missing.

Also, please check if there are any problems with the data source itself. Here I have helped you to find threads where you have had the same problem and where you can try to find a solution.
