It seems like
$observer is not always an object, but can also be of type null . Maybe add an additional type check?
If a variable is not always an object, we recommend to add an additional type check to ensure your method call is safe: function someFunction(A $objectMaybe = null)
{
if ($objectMaybe instanceof A) {
$objectMaybe->doSomething();
}
}

This code seems to be duplicated across your project.
Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository.

It seems like you allow that null is being passed for a parameter, however the function which is called does not seem to accept null.
We recommend to add an additional type check (or disallow null for the parameter):
