covr::codecov fails when vetiver is a package dependency.

[B0ydT]

While troubleshooting a a failure in a CI/CD pipeline, I found that a covr::codecov call in GitHub Actions broke when I added vetiver as a package dependency. I was very surprised when I was able to replicate this locally; simply removing and restoring vetiver would fix and then break the test.

I even created a barebones test repo (https://github.com/B0ydT/covr-test) - the full error message is included in the README. With a minimal package and testing structure covr works just fine (B0ydT/covr-test@3c9fdc6), but as soon as I add a dependency on vetiver it fails (B0ydT/covr-test@546ff23).

I couldn't find any references to a known conflict between covr and vetiver and scanning the issues page here I was unable to spot any similar errors. I have zero guesses as to the root cause of this, so any advice would be much appreciated.

Cheers,
