Describe the bug

When deploying to production using pythonExtension and a nested requirements.txt, the build fails with following logs:

#11 DONE 82.8s

Using the exact same requirements.txt in the root folder works as expected.

Also, a warning stating...

▲ [WARNING] [pythonExtension] Both options.requirements and options.requirementsFile are specified. requirements will be ignored.

...occurs although no requirements: [] is present.

To reproduce

We initialized the basic python crawl example and moved the requirements.txt to the python folder.

I can confirm that requirements.txt in a nested folder (not the root) failed. I move mine to the root folder and now it's okay.
