Callback URL mismatch issue

Here is what I have setup in “Allowed Callback URLs”, snippet from my log:

    "authorized": [
      "http://localhost:3000/api/auth/callback",
      "https://<appname>.vercel.app/api/auth/callback"
    ],
    "attempt": "https://'https://<appname>.vercel.app'/api/auth/callback",

Note the attempt – any idea why the URL is getting jammed between https:// … ‘/api/auth/callback/’?

Localhost is working fine.

I have .env.local and .env.production files set, each one holding respective AUTH0_BASE_URL.

Not clear how to mark this item as resolved but it is. Simply needed to update AUTH0_BASE_URL and strip out ‘https://’ so value gets injected correctly into the attempt (request).
