Ignore_notifier_if settings are not respected in non-Rack usages such as background jobs.

[synth]

Steps to reproduce

Given: ExceptionNotifier is configured with:

ignore_notifier_if: {
        email: ->(env, exception) { ... }
      },

And an exception notification is manually sent such as through a background worker with:

rescue => e
  ExceptionNotifier.notify_exception(e)
end

Expected behavior

The ignore_notifier block should be called and respected.

Actual behavior

The ignore_notifier block is not called nor respected. This is likely because the ignore block is only set via Rack, so any non-Rack usages of ExceptionNotifier will not retain the ignore settings.

System configuration

Rails version:
Rails v6+

Ruby version:
Ruby 2.7

I have been struggling with the same issue
The problematic code was:

if options.key?(:ignore_notifier_if)
  rack_ignore_by_notifier = options.delete(:ignore_notifier_if)
  rack_ignore_by_notifier.each do |notifier, proc|
    ExceptionNotifier.ignore_notifier_if(notifier) do |exception, opts|
      opts.key?(:env) && proc.call(opts[:env], exception)
    end
  end
end

Thus the notifier does not work if env is not set

Giving any non null value for env solved the issue for me:

 ExceptionNotifier.notify_exception(e, env: request.env)
