The error message is telling you that the read
method of GenericHander
is an instance method, not a classmethod. You’ll need to instantiate the object before you can call the method.
Without knowing anything more about the class or method, this might work:
handler = GenericHandler()
results = handler.read(request, uuid)
but the instantiation call might need some parameters, which should be documented.
