Triage Reactive Web is down

@gl-quality/eng-prod - it seems that triage-reactive-web is down again. I noticed a few applications of ~"feature::maintenance" not applying ~feature.

I'm seeing errors at https://console.cloud.google.com/kubernetes/deployment/us-central1/triage-serverless-prod/triage-serverless-12690061-production-2/triage-web/logs?folder=882286565318&project=gitlab-qa-resources&supportedpurview=project

bundler: failed to load command: puma (/srv/rack/triage/vendor/bundle/ruby/2.7.0/bin/puma)
Bundler::GemfileNotFound: /srv/rack/triage/Gemfile not found 

I'll try to look into this as I can between catch-up meetings but would appreciate some help on this.
