[turborepo] Regression - Using turbo prune was working without turbo.json, fails since 1.7.1

[maximveksler]

What version of Turborepo are you using?

1.7.1

What package manager are you using / does the bug impact?

pnpm

What operating system are you using?

Linux

Describe the Bug

I'm using turbo prune as part of my docker ci/cd flow, other than for prune a different build system is handling the test/lint/build flow, since turbo has support for pnpm workspace projects discovery no turbo.json was required.

Working 1.7.0

Example for behavior in 1.7.0

Hi @maximveksler, this should be fixed in 1.7.3. Please reopen #3570 if the issue persists after updating your turbo version.

@chris-olszewski, please note the regression occures on 1.7.3 as well

@chris-olszewski this seems to be a seperate issues from #3570, perhaps reopen this issue instead of keep #3570 opened?
