Walkthrough

The update adds an explicit nil check for the function variable within a loop over Cloud Functions in the GCP provider code. This prevents a runtime panic when a nil function is encountered, ensuring that the code safely skips processing such entries.

Changes

File(s) Change Summary
pkg/providers/gcp/function.go Added a nil check for the function variable in the Cloud Functions iteration loop to prevent panics.

Poem

A hop and a skip through the GCP,
I found a nil that shouldn’t be!
Now with a check, I bounce along,
No more panics—just code that’s strong.
🐇✨
Safe and sound, the functions run,
Debugging woes? I’ve fixed that one!

30-30: Good defensive programming addition!

Adding the function == nil check is an important guard that prevents a potential nil pointer dereference panic. If a nil function object was encountered in the loop, the original code would have attempted to access function.HttpsTrigger, resulting in a runtime panic. This change ensures that the code safely skips processing in such cases.

This fix correctly addresses the issue referenced in #681.
