When using Bugsnag within a Rails app, you must use the
before_bugsnag_notify macro within your
ApplicationController (or similar) to add custom info. I tried to be clever, using the
Bugsnag.before_notify_callbacks manually in an initializer. This didn’t work. My assumption is that
Bugsnag.before_notify_callbacks.clear is called somewhere internally in the
It pays to read the Bugsnag ruby docs.
