Hi,

Recently I started seeing errors in a few repositories like this when using the action:

Error: No file in /home/runner/work/pytest-cpp/pytest-cpp matched to [**/requirements.txt or **/pyproject.toml], make sure you have checked out the target repository

AFAICT nothing has changed in the repositories significantly, in fact the errors appeared during pre-commit updates.

Is a requirement for projects to always have a pyproject.toml in the root now? Or something else?

Links to the failures (all of them are using the latest version, 1.5.3):
