[BUG] EMFILE: too many open files

[Antoine4011]

I'm moving from next on pages to the open next adapter.
I can successfully deploy from local but when trying to setup github deployment, I keep getting this error during dependencies install.

15:43:50.155 | .../node_modules/@swc/core postinstall: Done

I've found several questions asked on the cloudflare discord related to this but no response (https://discord.com/channels/595317990191398933/1347568839382138910 and https://discord.com/channels/595317990191398933/1363620455730253905), so I'm trying here.

Appreciate any help :)

I have exact the same problem, and got no response from Cloudflare Discord, either.

Could you try to create a minimal repro and share it as a link to GH repository?

Try deleting node_modules, lock file and reinstalling deps.

Hello @escwxyz, I've tried this. It worked one time, then on the next build it failed. So I'm afraid a minimal repro is going to be hard as it's not consistent 😓

I too have the same issue

I have exact the same problem, and got no response from Cloudflare Discord, either.

I fixed my issue by removing some routes (deleting about 70 page.tsx files), problem solved.
