Post setup python → Error: unexpected end of JSON input

[alunduil]

Description:

In alunduil/template.py, I have a Publish to PyPi action that consistently fails on the "Post setup python" step. The output is: "Error: Unexpected end of JSON input"

Action version:

actions/setup-python@v4

Platform:

• [ x ] Ubuntu
• macOS
• Windows

Runner type:

• [ x ] Hosted
• Self-hosted

Tools version:

poetry 1.4.1
Python 3.10.6

Repro steps:

My workflow file is public and available at https://github.com/alunduil/template.py/actions/runs/4520441086/workflow

Expected behavior:

I expect this step to finish without errors as the workflow is otherwise successful.

Actual behavior:

Erroring in post-processing indicates the run fails when it has already accomplished its goals.

Hello @alunduil. Could you please try to specify python-version: "3.10" ?

@dmitry-shibanov, it looks like the setting resolves my issue, but I'd prefer to use the defaults: https://github.com/alunduil/template.py/actions/runs/4546269063 .

I just wanted to let you know that I'll leave this here for you to decide if it's worth investing more time in. Thanks for the quick responses!

Hello @alunduil. We released a new version of the action with changes to throw a warning if cache paths can't be found with possible solutions to the error.

For now I'm going to close the issue.
