Vercel domain

[0xSMW]

Hello, I'm hosting on Vercel with my domain, however the app continually uses the deploy URL instead of the project URL. This causes issues with the oAuth handoff to Google. Is there a config I missed somewhere to force the app to always use the project or ENV-defined URL?

To ensure your application uses the project or environment-defined URL instead of the Vercel deploy URL, you should set the NEXT_PUBLIC_WEBAPP_URL environment variable to your desired project URL. This variable is used to determine the base URL for the application. If it's not set, the application defaults to using the VERCEL_URL environment variable, which is automatically set by Vercel to the deploy URL ^[1].

Additionally, make sure that the NEXTAUTH_URL is set correctly for OAuth handoff. If NEXTAUTH_URL is not explicitly set, it defaults to NEXT_PUBLIC_WEBAPP_URL with /api/auth appended to it ^[1].

By setting these environment variables in your Vercel project settings, you can ensure that the application consistently uses your specified project URL.
