Regression in Browser Rendering: PDF timeout
When generating PDF:
I tried setting the timeout config to 0 (indefinitely), and it still fails (different error). Yesterday, it worked just fine. I used the same code in Browserless, it works.
Screenshot works fine.

no time outs on my end using pdf method. generating 10-15 page count documents
still going on?
are you using browser rendering with Queues?
@ajgeiss0702 yes, it was working until recently
FYI I'm generating with background and some images
Browser rendering in queues is very unstable for some reason. I would call browser rendering from a DO and call that DO from the queue
And the resulting PDF is >10MB for some reason. Although screenshot is <100kb
That's interesting. I will try it thanks!
@TW I am also generating PDFs with images.
There is an issue with chromium pdf renderer that redraws images as pngs if they need to be cropped or scaled in anyway. The resulting png is easily 10x the original image size.
To get around this problem I made sure to resize the image (in pixels) on the server side before serving to my page template for the pdf. The image is resized for the desired page size (A4). Jimp works well in workerd environment to perform this if you serving images directly from R2.
By resizing the image to what your pdf template actually needs (assuming legal size A4) it will greatly reduce PDF file size and speed up rendering times.

PDF file too large · Issue #458 · puppeteer/puppeteer
The PDF file obtained by HTML conversion is too large. Is there any way to compress it?
Hi, I'm also running into the same problem. PDF generation has never failed before, and now I can not generate a single PDF that contains an image. My images are already resized to the smallest size possible server-side.
I'm not using queues, simply rendering in a worker.
What's the issue? Can you share an error message
The exact same error as above:
TimeoutError: waiting for Page.printToPDF failed: timeout 30000ms exceededAny more details you can share about the PDF document?
