Bad error message on failed requirements.txt installation

I had a bad version that did not actually exist in my requirements.txt, and sls deploy output this:

Seems like the error throwing code has a bug.

Changing packRequirements to false allowed my serverless deployment to go through as well.

I’m facing similar issue. Is there a temporary solution?

When I remove packRequirements: true from my serverless.yml, that seems to fix it. Just make sure you have werkzeug in your requirements
