Timeout when processing pdf in Github Action

[codingluke]

Dear Marp Community
I use marp-cli since 2 years together with github actions. Since lately I experiance some timeout errors when generating pdfs. Locally it works perfect and fast. Does anybody expericance the same?

• Link to the deployment.yaml
• Linkt to the package.json

THX a lot!

@yhatt I could actually reproduce this behaviour with the official marp-cli docker image locally.

With the old PUPPETEER_HEADLESS_MODE it fails caused by headless false or so...

docker run --rm --init -v $PWD:/home/marp/app/ -e LANG=$LANG -e marpteam/marp-cli operatoren.md --allow-local-files --pdf
[  INFO ] Converting 1 markdown...
[  WARN ] Insecure local file accessing is enabled for conversion from
          operatoren.md.
[ ERROR ] Failed converting Markdown. (Protocol error (Page.printToPDF):
          Printing failed)

With the NEW PUPPETEER_HEADLESS_MODE it fails caused by the timeout, like in the github actions.

docker run --rm --init -v $PWD:/home/marp/app/ -e LANG=$LANG -e PUPPETEER_HEADLESS_MODE=new marpteam/marp-cli operatoren.md --allow-local-files --pdf
[  INFO ] Converting 1 markdown...
[  WARN ] Insecure local file accessing is enabled for conversion from
          operatoren.md.
[ ERROR ] Failed converting Markdown. (waiting for Page.printToPDF failed:
          timeout 30000ms exceeded)

locally outside a docker image it works perfectly.

The protocol error should have been fixed in the latest image. It seems to be brought by (incompatible) major update of harfbuzz: marp-team/marp-cli#539

I just figured out some interesting use-cases:

1. I use the kroki plugin, which makes requests to kroki.io, without the mermaid graphs it works for the operatoren.md deck
2. In another deck I reference an image by http and not locally. This deck also has a timeout. When removing the external image it works.

It seems to me that accessing external ressources are problematic with puppeteer. The html file generation works fine.

This all used to work for 2 years.

Ok, here I can prove, github actions somehow are blocking external requests, a simple curl to the image I referene is also not working.

It seems to be github actions running in different regions. After re-running the curl worked...

Very strange, I close this discussion and will have an 👀 on this.
