Next.js: Next build fails with firestore dependency in serverless mode

[eugrdn]

Bug report

Describe the bug

When using firestore as a dependency next failed on the build step.
Hack with webpack-asset-relocator-pluging doesn't solve the issue as well, it causes another error though (gRPC binary module was not installed instead of package.json does not exist at /package.json w/o it)

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Clone this repo https://github.com/eugrdn/nextjs-serverless-firestore-issue
2. yarn install
3. uncomment 3rd line in next.config.js
   3*. remove webpackAssetRelocator usage if needed
4. yarn build

Expected behavior

Build step passes successfully

Hey can you try next@canary?

[eugrdn]

Do you mean next package version?
I've just tried with ^9.0.4-canary.6 and it didn't work as well

[timneutkens]

Are you deploying on Now?

[eugrdn]

Yes, but here the issue isn't with a deploy but with a build step

[timneutkens]

You'll want to set target: 'experimental-serverless-trace', the Now builder does this automatically.

Hey @timneutkens! Thanks, that's working!
