Why This Fix Works in Production
- Trigger: AttributeError: 'NoneType' object has no attribute 'label'
- Mechanism: The graph classes do not check types when comparing for equality, leading to AttributeError
- Why the fix works: Adds type checking to the __eq__ method in the graph classes to prevent AttributeError when comparing with incompatible types. (first fixed release: 7.1.0).
- If left unfixed, the same config can fail only in production (env differences), causing startup failures or partial feature outages.
Why This Breaks in Prod
- The graph classes do not check types when comparing for equality, leading to AttributeError
- Surfaces as: AttributeError: 'NoneType' object has no attribute 'label'
