          @gengjiawen can you open an issue for this? I can't help without more information or a repro. Thanks!

@siddhsuresh Can you take a look, thx.

[gengjiawen]

remove eval works for me. My guessing is that eval won't compatible with minifier.

[tordans]

@gengjiawen can you be a bit more specific? Thanks!

We are also having this problem...

patch node modules like this (I am using pnpm)

thanks for the issue @gengjiawen! I will take a look today.

Does this happen locally for you? Since I am no longer able to replicate this after the latest fix.

[gengjiawen]

Does this happen locally for you

If you refer to the deploy issue, The deploy issue only happens on nextjs. My local yarn start works.

[siddhsuresh]

okay thanks for the info. will keep that in mind and debug

[cfragkos]

probably related to #4309. Please fix it fast

[siddhsuresh]

@gengjiawen where is getBlitzContext being imported from? if you are importing from "@blitz/auth" instead import it from "app/blitz-server"

@gengjiawen where is getBlitzContext being imported from? if you are importing from "@blitz/auth" instead import it from "app/blitz-server"

import from blitz-server will result in build error.

Attempted import error: 'setupBlitzServer' is not exported from '@blitzjs/next' (imported as 'setupBlitzServer').

adding a new issue: #4310

[gengjiawen]

since this has been 3 weeks, I have created #4311 to fix this issue.
This fix all the issues I run into in productions.

Hey folks, we have investigated, can reproduce, but so far are unable to understand what is happening on Vercel.

Are any of you able to reach out to Vercel support and enlist their help?

[cfragkos]

Yes I am in contact, and got them to investigate, they were quick to blame the 3rd party dependency, but I pressed them after investigating the source code that the way you import and use debug is not wrong and it's their problem, so it seems they will look into it, I suggest you also reach out because you have more technical knowledge to explain than me

[cfragkos]

Got my answer today

Hi again,

Thank you for waiting. I have reviewed this issue with our team's framework-related expert and can confirm that investigating why the "debug" package is not working on Next.js 14 would require implementation-level debugging which is not in the purview of this support team.

The Blitz.js repo is the best place for this, so, that you're able to get support from framework developers and maintainers.

If there are any other platform-related Qs or issues that you may have, do let me know!
