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?

Could you please tell us which data source would you like to connect to?
There are some similar cases about SharePoint folder data source you may refer to :

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?
