Hi

Thanks for reaching out to Microsoft Q&A.

Are you sure it is json file type? from the screenshare you have shared the 'getjson' activity couldn't read the file and subsequently couldn't preview also. Have you tried raising a support ticket with microsoft? if not I would advise you to check and confirm and then raise a feature request.
