timeout

[ ERROR ] Failed converting Markdown. (Navigation timeout of 30000 ms exceeded)
What should I do

• Confirm if you have a stable connection to network. Marp conversion may require to fetch network resources while conversion, such as contents used in Markdown, Web Fonts by the theme CSS, and KaTeX Web fonts provided by jsDelivr CDN.
• Try HTML export instead of PDF and PPTX. It's free of any timeouts. And you also can try to convert HTML into PDF by using Chrome/Chromium-flavored browser (Menu -> "Print" -> Choose "Save as PDF" in the Destination)

Thank you

I am having the same problem. I don't know if it is only because the presentation is big (33 pages) or if there is something else breaking it, but I am using PUPPETEER_TIMEOUT=600000 and it still didn't finish before timeout. Is there anything I could do to help debug this?

[yhatt]

Try --debug=true or --debug=all option: marp-team/marp-cli#646 (comment)

Sorry I have not been clear enough. I am using VSCode, is there an option to debug through it? Something similar to the pupeteer env var maybe

[yhatt]

Marp for VS Code outputs logs into the console, that can show in the developer tools (Developer: Toggle Developer Tools), but it does not provide an extension setting to show detailed debug logs.

If you want it, try to launch VS Code with DEBUG environment value as marp-cli* (Output logs with the filter of marp-cli prefix: equivalent to --debug=true) or * (Logs from all dependencies that includes Puppeteer: equivalent to --debug=all). It is backed by debug module.

DEBUG="marp-cli*"

DEBUG="*"

Just for whoever might get into a similar problem in the future: the main problem in my case was not having chrome installed, it was using firefox by default and timing out. After installing chrome it was an instant execution.

UPDATE: Marp CLI v4 and later versions are providing --browser-timeout option to set the custom timeout duration for the browser that is used for generating PDF, image(s), and PowerPoint document.

# Set the browser timeout to 60 seconds
marp foobar.md --pdf --browser-timeout 60

# Disable the browser timeout by setting it to 0 seconds
marp foobar.md --pdf --browser-timeout 0
