This is actually a duplicate of #124, and the rollout of that fix is still pending (should be live in the next day or so).

Here's a working deployment after I set the env var as described in my comment on the other issue: https://vercel-remix-fetch-353n1cyuk-uncurated-tests.vercel.app/login

I applied the solution you provided to my company project, but unfortunately, the issue persists.
