Quick Fix: Do not specify the scheme (http:// or https://) in the Authorized domain field. This field does not accept localhost addresses. Instead, skip this field for test applications and add your domain address with the appropriate endpoint in the Authorized redirect URIs section in the Credentials menu.
The Solutions:
Solution 1: Invalid Domain Specification
The error arises because the Authorized domain field in the OAuth consent screen expects a valid domain name without a scheme (http:// or https://). Localhost addresses like "http://localhost:3000" are not accepted.
Resolution:
Skip the Authorized domain field when configuring OAuth2 for your test application. Specify the authorized redirect URIs in the Credentials menu instead. Use your domain address with the appropriate endpoint, for example:
https://yourdomain.com/auth/callback
Solution 2: Configure Hosts File
To resolve the issue, you can edit your /etc/hosts file to add an entry for your domain. For example:
127.0.0.1 test.cc
Replace "test.cc" with an arbitrary domain name of your choice. Save the file and run your development server locally using the specified domain instead of localhost:3000, e.g., test.cc:3000.
Once done, submit the specified domain as an authorized domain in your OAuth consent screen. This will allow you to use the specified domain for OAuth authentication without encountering the "Invalid domain" error.
Solution 3: Skip Authorized domains
The "Authorized domains" field in the OAuth consent screen does not accept localhost addresses. If you are setting up OAuth2 for a test application, skip this field. Instead, specify the Authorized redirect URIs in the Credentials menu. Enter your domain address and the appropriate endpoint to complete the setup.
