Seeking Help with "html-pdf" Package Error on Render.com

[Faruk]

I’m currently facing an issue with the “html-pdf” package in my Node.js backend deployed on Render.com and I’m seeking some assistance from the community.

Here’s the situation: I have integrated the “html-pdf” package (version 2.2.0) into my Node.js application to generate PDFs. Locally, everything works perfectly fine, and I’m able to generate and download PDFs without any issues. However, when I deploy the Node.js backend to Render.com and attempt to download a PDF, the process fails, and I receive the following error:

 Error: html-pdf: Received the exit code '1'

I dont really know what is wrong so I also dont know what I should try

I would greatly appreciate it if anyone could provide insights or guidance on how to tackle this issue. If you’ve encountered a similar problem or have expertise with the “html-pdf” package, your input would be invaluable.

Thank you in advance for your time and assistance. If you need any additional information, please feel free to ask. Your help is highly appreciated!

I changed my node pdf logic to use puppeteer because that was recommend but now I receive

  Error: Could not find Chrome (ver. 116.0.5845.96). This can occur if either
Aug 30 10:56:19 PM   1. you did not perform an installation before running the script (e.g. `npm install`) or
Aug 30 10:56:19 PM   2. your cache path is incorrectly configured (which is: /opt/render/.cache/puppeteer).
Aug 30 10:56:19 PM  For (2), check out our guide on configuring puppeteer at https://pptr.dev/guides/configuration.
