Need help getting google-python template and poetry to work

Serverless Framework
1

Hi, I am trying to use the framework together with GCP and Python for the first time. I like poetry and would like to use it in this project. I followed the sample application and some blog post about using poetry with serverless.

When I try sls deploy I am hitting the following error. Note that I went to python38 as runtime.

Error: python38 not found! Try the pythonBin option.
at pipAcceptsSystem (/Users/username/dev/cloudfunctions/node_modules/serverless-python-requirements/lib/pip.js:104:13)

This error stems from the serverless-python-requirements plugin. Ideally, the python binary as well as pip should be controlled by poetry - and not be the system python. Am I missing something in my setup? Here is my serverless.yml and pyproject.toml.

service: cloudfunctions

provider:
  name: google
  stage: dev
  runtime: python38
  project: notShown  

frameworkVersion: '2'
plugins:
  - serverless-google-cloudfunctions
  - serverless-python-requirements

package:
  exclude:
    - node_modules/**
    - .gitignore
    - .git/**

  first:
    handler: http
    events:
      - http: path
