What is the code size limit for deploying a Next.js project using "Pages"?
I deployed a Next.js project using "Pages", and the build was successful. However, I'm getting a 500 error when I try to access the site. I'm not sure if this is related to the size of my codebase.

It would fail on deploy if it was size related. Tail your function and look at the logs
?pages-logs

or with Wrangler:
wrangler pages deployment tail [deploymentId/url]Oh yes, thanks for your reminder, I saw the error："message": [

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.
