Demo Server failing due to CORS! #149

Closed epugh closed 2 years ago

I wanted to try out the demo server, to see how this worked, but am getting CORS errors:

Access to XMLHttpRequest at 'https://link-thumbnailer-demo.herokuapp.com/thumbnails/?url=https:%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D0XFudmaObLI' from origin 'http://link-thumbnailer-demo.herokuapp.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

It just works for me but looking at your screenshot, you are not on the HTTPS version of the demo.

Of course! I tried it out in IRB and it worked.

You might be interested in this PR for a project I steward, where I am wrestling with the same issue ;-)
