Hey @debkanchan, thanks for reaching out and for providing a detailed report. I discussed this with our engineering team. Currently, pnpm is supported, however pnpm workspaces is not. For now, I’ll mark this as a feature request.

Hi @aalej, just thought I'd chip in and mention a similar discussion that was started here: #7206 (reply in thread)

Looking forward to see official support for pnpm workspaces at some point in the future.
