Puppeteer on Azure Functions Linux throws exception “Failed to launch the browser process!”

Question

I'm trying to start a headless chrome with a puppeteer in Azure Functions on Linux.

What do I do? I have a “Function App” that looks this way:

And I have a function:

I build this function remotely this way:

func azure functionapp publish {appname} --build remote

And this is what I get when I try to run a function:

Result: Failure
Exception: Failed to launch the browser process!
/home/site/wwwroot/node_modules/puppeteer/.local-chromium/linux-1011831/chrome-linux/chrome: error while loading shared libraries: libgobject-2.0.so.0: cannot open shared object file: No such file or directory

I've seen this topic already (Puppeteer throws launch exception when deployed on azure functions node on Linux) but they recommend do a remote build, which I do and it still doesn't help.

Maybe I'm using wrong App Service Plan, but I checked and there were nothing related to special linux setup there.

Answer 1

The reason was that I was indeed using the wrong App Service Plan. I needed a “Function App” one. When I recreated a function with the right service plan, everything worked just fine.

Answer 2

• I was able to deploy the azure function without the use of func azure functionapp publish {appname} --build remote. I did it using the visual studio code.

• But before that I installed the puppeteer inside the function folder using

npm install puppeteer

• Then I added the node_modules name in the .funcignore file.

• Then I added the following setting in setting.json in the .vscode folder

   "azureFunctions.scmDoBuildDuringDeployment": true

• Then deploy the function normally through vscode
