Ubuntu – Devops Pipeline not installing Playwright correctly

I am trying to create a Devops Pipeline to deploy to a Python Azure Function App. Using Vs code I can successfully deploy to the function app and everything works 100%. I had to add 2 app settings mentioned here (https://github.com/anthonychu/20220303-python-func-playwright) to get it working.

Next steps was to create a Pipeline in Azure Devops. I tried using the classic editor and the YAML creator but I just cant get Playwright to install. I keep getting the error:
Looks like Playwright was just installed or updated. Please run the following command to download new browsers: playwright install <3 Playwright Team.

Anyone here managed to get a Devops pipeline to deploy to a Python Azure Function App V2 that includes Playwright to work yet?

Basically I need to figure out how to run playwright install chromium as a post build task. I tried adding a POST_BUILD_COMMAND app setting but it doesn’t seem to run when I deploy using the Pipeline, its does however run when deploying using VS Code

My current YAML:

pool:
  vmImage: ubuntu-latest

steps:
- task: UsePythonVersion@0
  displayName: "Set Python version to 3.10"
  inputs:
    versionSpec: '3.10'
    architecture: 'x64'

- bash: |
    if [ -f extensions.csproj ]
    then
        dotnet build extensions.csproj --output ./bin
    fi
    pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt

- bash: |
    sudo mkdir -p /home/site/wwwroot
    PLAYWRIGHT_BROWSERS_PATH=/home/site/wwwroot
    python -m pip install playwright
    PLAYWRIGHT_BROWSERS_PATH=/home/site/wwwroot /opt/hostedtoolcache/Python/3.10.13/x64/bin/python3.10 -m playwright install chromium
  displayName: 'Install Playwright'


- task: ArchiveFiles@2
  displayName: "Archive files"
  inputs:
    rootFolderOrFile: "$(System.DefaultWorkingDirectory)"
    includeRootFolder: false
    archiveFile: "$(System.DefaultWorkingDirectory)/build$(Build.BuildId).zip"

- task: PublishBuildArtifacts@1
  inputs:
    PathtoPublish: '$(System.DefaultWorkingDirectory)/build$(Build.BuildId).zip'
    artifactName: 'drop'

    1. Create a yaml pipeline from the template:
      enter image description here
    2. Use the following scripts to install chromium in the yaml pipeline.
        - bash: |
        pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt
        cd ./.python_packages/lib/site-packages
        python -m playwright install chromium 
      workingDirectory: $(workingDirectory)
      displayName: 'Install application dependencies'
      env:
        PLAYWRIGHT_BROWSERS_PATH: $(workingDirectory)

    1. Add an app setting PLAYWRIGHT_BROWSERS_PATH=/home/site/wwwroot in the function app.
      enter image description here

    2. Then the function works as shown below.

    I am running a jenkins piple line and I use the Playwright image instead. I am quoting the Playwright documentation. I am using the Jammy image myself in my pipeline

    docker pull mcr.microsoft.com/playwright:v1.41.1-jammy

    Have you tried that? That could be a potential solution and you won’t have to hunt for the right version of chromium and install it. This comes preinstalled with Playwright browsers.
