Issue Summary

A summary of the issue. This needs to be a clear detailed-rich summary.

Steps to Reproduce

Same issue as a previous ticket #1908

I tried this solution 'Their docs are not fitting for this repo, though. Needed to change the build command to cd ../.. && yarn run build and install command to yarn install --prefix=../..."; however, that didn't work either.

Any other relevant information. For example, why do you consider this a bug and what did you expect to happen instead?

Technical details

• Browser version, screen recording, console logs, network requests: You can make a recording with Bird Eats Bug.
• Node.js version
• Anything else that you think could be an issue.

[00:29:50.842] Please check the following, and reach out to support if you cannot resolve the problem:
[00:29:50.842] 1. If present, be sure your build script in "package.json" calls next build. 2. Navigate to your project's settings in the Vercel dashboard, and verify that the "Build Command" is not overridden, or that it calls next build. 3. Navigate to your project's settings in the Vercel dashboard, and verify that the "Output Directory" is not overridden. Note that next export does not require you change this setting, even if you customize the next export output directory. Learn More: https://err.sh/vercel/vercel/now-next-routes-manife

Did you figure this out? I'm having the same issue.

[RR-Helpdesk]

Nope, I tried for about 6 months and finally gave up. No one from the app dev seems to respond either.

@REVREBEL I started over and then followed these settings, and it worked https://developer.cal.com/self-hosting/vercel

Added the ENV variables and changed the settings with these parameters:

Set the root directory to apps/web

cd ../.. && yarn build

I wasn't using calcom but perpetually got this exact error. This likely won't be a direct fix since calcom is wrapping your vercel deployment through Next env vars; but for what it's worth: I had to change my direct dependency "next": "latest" to "next": "12" (anything but latest).
