🧪 Relevant tests	No
🔍 Possible issues	Possible Bug: If the method `ToSlice()` does not handle nil or empty collections as expected, it might still lead to a panic or unwanted behavior. It's crucial to ensure that `ToSlice()` is robust against such cases.
🔒 Security concerns	No

PR Code Suggestions

Category	Suggestions
Possible issue	Add a nil check to prevent potential runtime panics. Ensure that the `Get` method call on `ap.slugToContainers` does not return `nil` before attempting to call `ToSlice()` on it. This will prevent potential runtime panics due to dereferencing a nil pointer. pkg/objectcache/applicationprofilecache/applicationprofilecache.go [257-259] -for _, i := range ap.slugToContainers.Get(apName).ToSlice() { - ap.containerToSlug.Set(i, apName) +containers := ap.slugToContainers.Get(apName) +if containers != nil { + for _, i := range containers.ToSlice() { + ap.containerToSlug.Set(i, apName) + } }
