Rendering throwing Errors: is it chrome, mkdocs, or the exporter?

[bvhme]

I'm trying to run the exporter in a GitHub codespaces on this repo: https://github.com/MinBZK/Baseline-Informatiebeveiliging-Overheid

I've ran install playwright chromium --with-deps in order to get playwright to run.

Now the rendering starts:

INFO    -  [mkdocs-exporter.pdf] Rendering 'ontwerp/nis2enbio.md'...

But it keeps throwing these:

ERROR   -  [mkdocs-exporter.pdf.browser] (error) Verhouding NIS2 en BIO2 - Baseline Informatiebeveiliging Overheid 2 (BIO2) [concept]
           Failed to load resource: net::ERR_FILE_NOT_FOUND

And after a minute it fails with a traceroute and:

playwright._impl._errors.TimeoutError: Locator.wait_for: Timeout 60000ms exceeded.
all log:
  - waiting for locator("body[mkdocs-exporter=\"true\"]") to be visible

Now, I really don't understand what is happening. Should I add the mkdocs-exporter attribute in a template?

This is likely the same issue as #59.

The ERR_FILE_NOT_FOUND is something I have on every page of my project as well, but it doesn't seem to have any adverse effects besides cluttering the terminal. My guess is that Playwright's Chrome is failing to load some resource, but annoyingly what that is isn't part of the error.

The waiting for locator error is something for which a minimized project example would be useful to find the cause. In #59, MkDocs ran successfully when not using the back cover or when removing the offline plugin. My current guess is that there might be a resource loaded by the back cover that messes with the Fetch API altered by offline and/or alters the body tag attributes.

Thanks. I had read that issue as well. I've tried disabling all plugins (except the exporter) and removing the covers. It has not changed this behaviour.

I am a bit at a loss at for where to look to solve this, is it playwright or something else? And why is it looking for body[mkdocs-exporter="true"]?

After the pdf module finishes rendering the pages for a PDF it sets the mkdocs-exporter attribute for the document.body element. This seems to be used as an indicator to tell the asynchronous processes when the pages are rendered.

mkdocs-exporter/mkdocs_exporter/formats/pdf/resources/js/pdf.js

Lines 26 to 46 in 0d4eae0

	/**
	* Invoked once all pages have been rendered.
	*/
	after: () => {
	if ('__MKDOCS_EXPORTER__' in window) {
	const pages = document.getElementsByClassName('pagedjs_pages')[0];
	if (pages) {
	if ('pages' in __MKDOCS_EXPORTER__) {
	pages.style.setProperty('--pagedjs-page-count', __MKDOCS_EXPORTER__.pages);
	}
	if ('page' in __MKDOCS_EXPORTER__ && pages.children[0]) {
	pages.children[0].style.setProperty('counter-set', `page ${__MKDOCS_EXPORTER__.page}`);
	}
	}
	}
	document.body.setAttribute('mkdocs-exporter-pages', document.getElementsByClassName('pagedjs_page').length);
	document.body.setAttribute('mkdocs-exporter', 'true');
	}

Are you able to create a minimal project that still exhibits this error?

Sadly so far not even disabling all other plugins seems to help me. I suspect the GitHub environment, which I'll check out next.
