Original GitHub issue: https://github.com/guyzyl/whatsapp-contact-sync/issues/229

I deployed this project, and it seems to work fine, but on the second step, when I click to authorize Google account I get this error.

How can I fix it?

Well, this is an issue with the setup of you're google app.
The guide:
https://developers.google.com/workspace/guides/create-credentials

The URI you have configured here must match with the URL you have in your browser while using the app
