Yes, I'm getting that also with Remix App Server. Switching to Express works.

This will be fixed by @mcansh's #4358

This was caused by NODE_ENV being set differently across different builds. The new dev server ensures NODE_ENV=development is set for all builds while it is running. Fixed in v1.16.
