Grover::JavaScript::UnknownError #253

Closed koenhandekyn closed 2 months ago

koenhandekyn commented 3 months ago

i'm trying to get grover running in a docker on hetzner cloud

using ENV GROVER_NO_SANDBOX=true using RUN npm install puppeteer@22 using RUN curl -fsSL https://deb.nodesource.com/setup_22.x using ARG RUBY_VERSION=3.3.4 using RUN npx puppeteer browsers install chrome

so the system is ubuntu with ruby 3.3.4, nodejs v22, puppeteer v22, the correct chrome get's installed and then i hit this very magical error which i don't manage to debug further.

first i was no ARM and i was installing manual chromium, pointing puppeteer to the executable and then hit exactly the same error. i thought it was ARM related, so switched the server to AMD/X86 but in the end i'm now hitting exactly the same issue.

ps: i'm using puppeteer@22 because v23 had a bug that was blocking me also. (see #252)

any help appreciated.

serious debugging later and with help of @eneagoe we traced it to JEMALLOC that was installed on the base image (a rails 7.2 app). clearing up LD_PRELOAD solved the issue (basically disabling JEMALLOC).

My understanding is that chrome has issues running with jemalloc, so you would need to compile Ruby with jemalloc specifically, or patch it. LD_PRELOAD is applying it to everything.

Not so sure about that @taylorthurlow. The issue is Chrome/Puppeteer/Node related. Using JEMALLOC in Ruby isn't going to come into play here. But as @koenhandekyn indicated, setting LD_PRELOAD to nothing will overload the system ENV setting, thus disable the loading of jemalloc. Although you'd likely want to check that there aren't any other libraries being pre-loaded as blanket clearing out that ENV var could cause other unexpected behaviours!
