Time out error #43
Description
Hi, when building to pdf from HTML, I got these errors
xaringanBuilder::build_pdf('xxx.html', complex_slides = T, partial_slides = T)
Error: Chromote: timed out waiting for response to command Target.createTarget
And sometimes
Error: Chromote: timed out waiting for event Page.loadEventFired
I'm wondering what may cause this and how may I prevent it?
Thank you!

I just tested. Same code works fine for a smaller HTML slides. Maybe it is due to the slide is too big and took a while to process, which is longer than the
timed outlimit and been killed? If so how do I adjust for thetimed outlimit?jhelvy commentedon Dec 14, 2021
Interesting problem, I haven't run into this before. Is there an html slide deck that you could link to so we could try and reproduce this error?

Not sure whether it is related, but I adjusted the size of some figures in the slides, now I don't see the error. I just opened a new issue #44 which might related to this

The image size is likely the root cause of the problem -- I'd be interested to hear how large the image was before you reduced the size.
This does bring up that both
pagedown::chrome_print()andchromoteallow us to configure the timeout when waiting for the page load and we could expose this cleanly inbuild_pdf().We'd add the
waitarg tochrome_print()here (the default is2) https://github.com/jhelvy/xaringanBuilder/blob/235c8c41d9e720fa48171fa8567839d2e042660d/R/pdf.R#L99-L102And
<ChromoteSession>$Page$loadEventFired()has atimeout_argument (not sure what the specific default value is there), which we'd want to set here https://github.com/jhelvy/xaringanBuilder/blob/235c8c41d9e720fa48171fa8567839d2e042660d/R/pdf.R#L123-L124albert-ying commentedon Dec 14, 2021
I used to have ~30 pictures, each ~ 5Mb. I also noticed that sometimes by setting
self-contain: true, the timeout error could be avoided. Probably because it take a long time to load pictures. It would be nice to be able to set the timeout limit as an argument frombuild_*functions in the future! Thank you so much!gadenbuie commentedon Dec 14, 2021
Ah that makes sense. 150MB of images isn't gigantic but it is fairly large. Check out the issue and linked Twitter thread in #26, there are some tips there about reducing the image size without losing quality!
