So I am trying to set up a Jenkins deploy pipeline. Almost everything seems
to be working fine, except for the last part of the job, which is to run
`wrangler publish` (to publish the site to Cloudflare Workers).
I have tried running it twice now, and both times, it will fail during the
job, and I will receive an error code "502" when I try to access my jenkins
server. The only thing that works is a full reboot of the server.
I have tried checking logs, but nothing much shows up. In jenkins.error.log
I see this:

Any ideas?
I have tried restarting nginx, that doesn't prevent the 502 error. However,
when I run `sudo /etc/init.d/jenkins restart` the jenkins server will
reboot and be online again.
When I go into the failed job, I see this at the very end, before the
server crashed:
memory allocation of 240904 bytes failedCreating placeholder flownodes
because failed loading originals.

Thinking this could be a memory related issue I went into
`/etc/default/jenkins` and updated `JAVA_ARGS` to `JAVA_ARGS="-Xmx4g
-XX:MaxPermSize=512m -Djava.awt.headless=true"` - but that didn't change
anything. I have verified I can run `wrangler publish` via terminal on the
server, without issues.
