Module not found: Can't resolve 'request' in '/vercel/path0/node_modules/.pnpm/google-gax@4.2.1_encoding@0.1.13/node_modules/google-gax/build/src

I'm getting this error during build time using @google-cloud/tasks in a turborepo(monorepo).

It seems to be directly related to pnpm, I'm using @google-cloud/tasks in another Vercel project which uses yarn, and the error is not triggered during build in this case.

Is pnpm supported?
