I have been struggling for weeks trying to open Drive picker on web app but i keep getting the same error : 400 redirect_uri_mismatch. I am using Appscript. Note : I use live server on visual studio to open the html file.

Here is the sample i copy past to try loading the Drive picker.

And of course, i changed the apiKey & the ClientId in the code to put mine.

Can someone knows why i kept getting this error ? Its seems a lot of people had been struggling with that error. Does the problem comes from Google Server ? Or, is there something missing in the code (github)

It looks like this when I open it with live server

I tried everything but I can't find what's the issue...
