Strange TimeoutError from Puppeteer\common\util.js

[Vikramsingh-karnot]

I have created a azure pipeline & I'm using marp cli on to convert md to pdf. But facing timeout error from util.js. These I'm getting in both linux agent as well as windows agent. I have also setup an chrome path. (tried with both chrome path & edge path.) But nothing worked. Trying to Resolve it from last 1 week but no luck. @yhatt Please help. Below is my pipeline powershell script.

  steps:
  - task: PowerShell@2
    inputs:
      targetType: 'inline'
      script: |

        $env:CHROME_PATH="C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"
        New-Item -Path ".\$(pdf_output)" -ItemType "Directory"
        marp --html --allow-local-files --theme $(Build.SourcesDirectory)/Stylesheets/marp-theme.css $(Build.SourcesDirectory)/slides.md --pdf -o $(Build.SourcesDirectory)/$(pdf_output)/slides.pdf

set PUPPETEER_TIMEOUT=80000 @yhatt I added it but I didn't worked same issue. And their is no resource constraint because I'm using a dedicated agent with 2vcpus & 8 GB of RAM.

[yhatt]

Try to disable timeout through PUPPETEER_TIMEOUT=0. And setting DEBUG=* env would help to get Puppeteer logs while converting.

[Vikramsingh-karnot]

After setting up above two env's it did not printed any special logs same error i got @yhatt . Modified Pipeline task

  steps:
  - task: PowerShell@2
    inputs:
      targetType: 'inline'
      script: |

        # Define the new path to add
        $newPath = 'C:\Users\docascode\AppData\Roaming\npm;C:\Program Files\nodejs;C:\Program Files\Google\Chrome\Application\;C:\Program Files (x86)\Microsoft\Edge\Application\'
        $currentPath = $env:Path
        $env:Path = "$currentPath;$newPath"
        $env:CHROME_PATH="C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"
        Write-Host $env:Path 
        npm install -g @marp-team/marp-cli
        marp --version
        New-Item -Path ".\$(pdf_output)" -ItemType "Directory"
        set PUPPETEER_TIMEOUT=0
        set DEBUG=*
        marp --html --allow-local-files --theme $(Build.SourcesDirectory)/Stylesheets/marp-theme.css $(Build.SourcesDirectory)/slides.md --pdf -o $(Build.SourcesDirectory)/$(pdf_output)/slides.pdf

If you are using PowerShell, you should use $env:PUPPETEER_TIMEOUT=0 and $env:DEBUG="*" instead of set (for cmd).

Yes, It worked got detail logs! But it got failed in the end. @yhatt

hey @yhatt any idea? or you want entire logs?

[yhatt]

I'm not familiar with Azure Pipelines and probably it's difficult to point out what happening accurately. So please don't rush me and don't emphasize frustrations just because you're in trouble. Maintainers and contributors are not support staff, and our open source projects are entirely voluntary.

Recommend to use GitHub Discussions instead of GitHub Issues for asking help to Marp community. See again our support guideline. https://github.com/orgs/marp-team/discussions https://github.com/marp-team/.github/blob/master/SUPPORT.md#how-about-github-issues

To debug your case, you should provide enough informations or minimal reproducible example that answerers can reproduce your environment. (e.g., Marp CLI version, Microsoft Edge version, and input Markdown files)

It is also worth trying to check:

• Can you convert the same Markdown in local environment?
• Can convert it with Google Chrome, instead of Edge (which is set in CHROME_PATH)?
• What happens if disabled browser sandbox through $env:CHROME_NO_SANDBOX=1?

[Vikramsingh-karnot]

Hey buddy, first of all, I'm not emphasizing frustrations on you so relax. I was just curious to know that's why I asked if you need any additional logs. 😊 I will try fix it!😊

[yhatt]

Uh ok, don't mind. Maybe I'm just tired. 🍵 I think that the context around CLI is important than extra logs.

Some environments are known as incompatible with Chromium sandbox. CLI will automatically disable sandbox if it is running on inside the container, but may be suitable to CI environment too.
