PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add nil check for uploader configuration to prevent template rendering failures The uploader configuration lookup should use $podScope.recorder.uploader.name instead of directly accessing .Values.videoRecorder.uploader.name to ensure consistent configuration inheritance and prevent nil pointer errors. charts/selenium-grid/templates/relay-node-deployment.yaml [36] -{{- $_ = set $podScope "uploader" (get $.Values.videoRecorder ($podScope.recorder.uploader.name | toString)) -}} +{{- if $podScope.recorder.uploader -}} +{{- $_ = set $podScope "uploader" (get $.Values.videoRecorder ($podScope.recorder.uploader.name | toString)) -}} +{{- end -}} Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion adds a crucial nil check that prevents template rendering failures when the uploader configuration is not defined, addressing a potential runtime error that could break the helm chart deployment.	8
