@vasco3 ,

What runner did you use? GitHub-hosted runner or your self-hosted runner?

On GitHub-hosted runner, you can try the following commands to see if the system local can be changed:

• On Linux

  # View information of current System Locale
  locale
  Set LANG to es-MX.UTF-8
  sudo update-locale LANG=LANG=es-MX.UTF-8 LANGUAGE
  Configure the locale parameter LC_TIME
  sudo update-locale LC_TIME=es-MX.UTF-8
  
  

• On Windows

  Set-WinSystemLocale -SystemLocale es-MX
  

• On macOS, using the “sudo languagesetup” command.

On the self-hosted runner, you can try to set the system local of the runner machine as Spanish (Mexico), also known as es-MX.

this is my setup and it is a Github-hosted runner

name: Unit Tests
on:

push:

branches:

- master

pull_request:

branches: [master]
jobs:

Jest:

runs-on: ubuntu-latest
strategy:
  matrix:
    node-version: [14.8]

steps:
  - uses: actions/checkout@v1
  - name: Run Tests
    run: |
      npm install 
      npm test

npm test runs well in my local, the problem is when it runs as a Github action.

not sure how could I run the update-locale command in yaml

@vasco3 ,

I have created an issue ticket (actions/virtual-environments#1650) to help you report the problem to the appropriate engineering team for further investigation and evaluation.
You can follow this issue ticket and add your comments to it.

thank you, I will follow up on there

    runs-on: ubuntu-latest

  matrix:

Thank you @al-cheb this is helpful. I’ll use this instead

I updated Node to version 16 and everything worked for me. Thanks
