[BUG] A `files` input with a trailing comma causes a traceback

[webknjaz]

Here's a concrete log: https://github.com/ansible/awx/actions/runs/10871115353/job/30164548007?pr=15527#step:6:53. This is the stack:

This is the input:

files: /home/runner/.ansible/collections/ansible_collections/awx/awx/tests/output/junit/ansible-test-sanity-action-plugin-docs.xml,

Obviously, this action parses the input as two file paths, the second one being an empty string which automagically notmalizes into a . which is a directory. This problem does not exist in codecov/codecov-action so the input processing probably doesn't reuse the same code.

Solution

I think that empty files should either be disregarded or output an actionable error instead of a traceback. I'd vote for disregarding since it's easier on tools that generate value for this input.

It seems to me that codecov-cli is called with -f '', though it's not logged there, so I assume there might also be a bug related to printing the invoked commands too.

Ah, it's visible here but '' isn't rendered: https://github.com/ansible/awx/actions/runs/10874452328/job/30171744063?pr=15527#step:6:30
