Hello. URL length is limited to 2097152 characters. This is an error chromium throws in console for very big html which contains few base64-encoded images: Refusing to load URL as it exceeds 2097152 characters. Unfortunately I can't share html that I'm trying to convert (those images contain some sensitive data)

What if it's a remote chrome instance, though?
How would you pass the temporary file?

This would only work for locally-running Chrome instances.

This does not appear to be an issue any longer. I was able to generate a 365 page PDF with the code below that used an HTML string composed of over over 2 million characters.

it('should generate from a lengthy HTML string', async () => {
  const options: HtmlPdf.CreateOptions = {
    port,
  };
  const filler = `
