There are certain situations where
_error
is loaded before_app
has had a chance to run. In those cases, we miss errors caught in_error
, because the SDK has not yet initialized (which currently happens the first time_app
runs). This injects the initialization code into_error
as well, to avoid such problems.(In order to not add extra code to the browser bundle, and because this has only shown up as a problem on the server side, for the moment this only does the injection when building the server bundle.)
Fixes #4168.
