This is my current configuration, but it's still throwing an error. I asked Gemini 2.5 Pro, and it said that next-intl is incompatible with pages.

For the compat flag to work you need to do another deploy

This isn't a new configuration; I set it up when I created these pages.

I solved this problem by updating to the latest version, 2025-05-05.
