Generator_failed error

[peter-de-boer]

I am trying to use elixir-pdf-generator in my web app.
First I have tried to use it with wkhtmltopdf, but it seems it does not handle all css correctly
So, I am now using it with Chrome-headless/Puppeteer.
I have installed it according to:

Eventually, if you are using Phoenix and you would like to have your npm packages installed localy, within the /assets/node_modules directory, simply run npm install chrome-headless-render-pdf puppeteer within assets/node_modules and pass prefer_local_executable: true option when generating the PDF like this:

PdfGenerator.generate(url, generator: :chrome, prefer_local_executable: true)

Bit if I try it with an existing url, I get:

[debug] {"/usr/local/bin/node", ["/home/peter/bw/_build/dev/lib/pdf_generator/priv/node_modules/chrome-headless-render-pdf/dist/cli/chrome-headless-render-pdf.js", "--url", "http://localhost:4000/factuur/test", "--pdf", "/tmp/MlUkqisz.pdf", "--paper-width", "8.26772", "--paper-height", "11.695"]}
{:error,
 {:generator_failed,
  "internal/modules/cjs/loader.js:883\n  throw err;\n  ^\n\nError: Cannot find module '/home/peter/bw/_build/dev/lib/pdf_generator/priv/node_modules/chrome-headless-render-pdf/dist/cli/chrome-headless-render-pdf.js'\n    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)\n    at Function.Module._load (internal/modules/cjs/loader.js:725:27)\n    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:72:12)\n    at internal/main/run_main_module.js:17:47 {\n  code: 'MODULE_NOT_FOUND',\n  requireStack: []\n}\n"}}

Any ideas?

Hi Peter was facing same problem solved by

cd deps/pdf_generator/priv && npm install

In my mix.exs

  { :pdf_generator, ">=0.6.2" },

[yugandharc9]

Used like this

 PdfGenerator.generate(html,page_size: "A3", delete_temporay: true,generator: :chrome, prefer_local_executable: true)

[jarvisjohnson]

these settings worked for me:

      PdfGenerator.generate(raw_html,
        page_size: "A4",
        prefer_local_executable: true
      )

I didn't have any config for the package in my config.exs, just that above with yarn add chrome-headless-render-pdf puppeteer in /assets

Thanks for pointing that out. This seems to be an incompatibility with newer Phoenixes
