Steps to Reproduce

1. Set ENABLE_EXPERIMENTAL_COREPACK to 1 in build settings
2. Set "packageManager": "[email protected]" in package.json
3. Set yarn install as install command

Build will fail with the following logs:

1. Execute yarn install locally and fix any encountered bugs.
2. Perform a local build and resolve any arising issues.
3. Finally, deploy locally using vercel (vercel CLI docs).

Have you resolved this? I deployed 8 hours ago and I am now getting this error. I have set it temporarily to use yarn v1 for it to "work"

[GauBen]

I gave up using corepack, I just use yarn 4 with global yarn 1 setup

As a hotfix, changing "type": "module" to "type": "commonjs" in root package.json has fixed it for me. (vercel@npm:33.7.0)
