We found extra characters at the end of JSON input.

Getting this error when doing a "from the web"

Details: "We found extra characters at the end of JSON input."

 

When I send the JSON to a validator it says that it is fine. How can I get more specific details on why it is complaining? There is no further detail in the trace file.

I would download the JSON from that API and then serve it from your own web app to figure out what are the needed changes. Then make your web app a proxy to the API and make those changes on the fly to the response.

This issue comes when we try to refresh data after uploading the pbix. When we connect to the rest API's in Power BI it works fine there.
