Awesome work with this project, everything deployed fine, however getting the following error in CloudWatch when running a PDF generation, this just gives a blank PDF in the browser as a result.

Hi @Taylorsuk, did you resolve this issue? I'm seeing the same thing and could need a hint where to look. thanks.

@jaypea I recall getting it working but I cannot remember what I did TBH, it was just a world of pain. Then I found the function so unreliable that I looked around for a 3rd part service. I stumbled upon Prerender.Cloud which has a simple Node Library and offers good value for money. Run a good 1000+ PDFs through the service without a single error and good response times considering it's transiting the atlantic. I spoke with Jonathan the founder and there is an option for an EU server if it's finantially viable for him.
