Playwright azure function doesn't install chromium Python based

Question

I tried to execute an azure function based on Python and get this problem

PLAYWRITH_BROWSERS_PATH=0 is already set, also I tried put playwright install on requeriments.txt
but it doesn’t work either. I’ve thinking in add a task in tasks.json on .vscode path but I don’t know how to do it.

Answer 1

PLAYWRITH_BROWSERS_PATH=0

Please make sure your above configuration was correct. There are some spelling mistakes in the settings. Its like PLAYWRIGHT_BROWSERS_PATH = 0

In your local.settings.json it should be

{

"IsEncrypted": false,

    "Values": {
    
        "AzureWebJobsStorage": "",
        
        "FUNCTIONS_WORKER_RUNTIME": "python",
        
        "PLAYWRIGHT_BROWSERS_PATH": "0"
    
    }

}

And In your requirement.txt file it should be

azure-functions
playwright==1.18.0

here we can see the playwright running in local as well as azure after deployment

You can solve this by installing the drivers into the function project and defining the location in PLAYWRIGHT_BROWSERS_PATH, as follows:

Create a bin folder in the project, here we want to store the drivers
Install the drivers in the bin folder using the following command, this installs the drivers in a pw-browers folder in the bin:

PLAYWRIGHT_BROWSERS_PATH=./bin/pw-browsers python -m playwright install

Define the path to the drivers in local.settings.json AND in the Azure function project itself:

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "PLAYWRIGHT_BROWSERS_PATH": "./bin/pw-browsers"
  }
}
