I am trying to connect to an API through the Web connector. The connection is working, but when I try to refresh I do get an error
'Web.Contents kan de inhoud niet ophalen van 'xxxxxxxxxx' (500): Internal Server Error.
When I try the URL in a browser the data is shown, so the URL is working, also in the Power Query editor the data is shown.
So why do I get this error?

Hi v-xicai,
I am using the Web data source and just filling in the url of the REST API. As I mentioned this URL is working in a browser, and also when I created the data source, but with refreshing I got the error.
Peter
Anyone a solution for this?
