Receiving "Usage Error" when trying to use pnpm within CI/CD

[mrdowden]

We have a PNPM project that works perfectly in local development, but when running in CI/CD (Bitbucket Pipelines using Docker) we receive the error Usage Error: This project is configured to use yarn. The thing is, we've never used Yarn on this project and don't use Yarn in any of our projects. Nothing within the project references Yarn in any way. The only place Yarn exists is that it's installed in the docker image alongside NPM and PNPM. Of note, we get the error doing so much as yarn -v in an attempt to verify the installed version.

Any idea why we might be getting this error? I haven't been able to find any similar issues in any online discussions.
