[thunderhunt]

Context:

• version (md-to-pdf -v): 5.2.4
• platform (Unix, macOS, Windows): Unix
• node version: v18.17.1

Describe the bug:

When you run to get the pdf of an MD file, some weird warning lands on the screen. check below.
Puppeteer old Headless deprecation warning:
In the near future headless: true will default to the new Headless mode
for Chrome instead of the old Headless implementation. For more
information, please see https://developer.chrome.com/articles/new-headless/.
Consider opting in early by passing headless: "new" to puppeteer.launch()
If you encounter any bugs, please report them to https://github.com/puppeteer/puppeteer/issues/new/choose.

Do you mean the message shows up in the terminal or in the generated PDF?

Same here

This will resolve itself soon enough with the next major version of puppeteer, I assume.

This happens because there is a new headless implementation, the previous one will be soon deprecated, the default option in md-to-pdf is still using it, this issue is resolved by changing the headless option to "new", it works fine, so is a simple update.

Temporary fix

const pdf = await mdToPdf(
      { content: "" },
      {
        launch_options: {
          headless: "new",
        },
      }
    );
