I got this error using different repro steps:
1. Declare a MonoBehavior class (MyClass).
2. Declare a function (MyFunc) that has a ContextMenu attribute in class (MyClass).
3. Declare a sub-class (MySubClass) that derives from the previously declared class (MyClass).
4. Add a component of type subclass (MySubClass) to a GameObject.
5. Right-Click on the component and run the function (MyFunc) from the context menu.
6. Error: "Failed to call function because it was null".
Steps to work around this issue:
1. Declare a MonoBehavior class (MyClass).
2. Declare a *virtual* function (MyFunc) that has a ContextMenu attribute in class (MyClass).
3. Declare a sub-class (MySubClass) that derives from the previously declared class (MyClass).
4. Declare a *override* function (MyFunc) for the previously declared virtual function.
5. Add a component of type subclass (MySubClass) to a GameObject.
6. Right-Click on the component and run the function (MyFunc) from the context menu.
7. Success.
