[rabernat]

This has been reported in two recent PR:

• style: add ruff and black to pre-commit #1459 (comment)
• Updated release notes for 2.16.0 #1471 (comment)

The failure occurs in this part of our CI

zarr-python/.github/workflows/python-package.yml

Lines 81 to 88 in 13cdbff

	- uses: codecov/codecov-action@v3
	with:
	#token: ${{ secrets.CODECOV_TOKEN }} # not required for public repos
	#files: ./coverage1.xml,./coverage2.xml # optional
	#flags: unittests # optional
	#name: codecov-umbrella # optional
	#fail_ci_if_error: true # optional (default = false)
	verbose: true # optional (default = false)

And the error message looks like

I am just parroting what I read here, but perhaps uncommenting this line from the CI workflow would address this.
