This can be done without changing the signature by storing the response on the object.

Suggested change

	self.exit_code = (
	response.get("StatusCode", 1) if response else 1
	) # we can assume this will be > 0
	error: dict[Any, Any] | None = (
	response.get("Error") if response else {}
	) # value from dict could be NoneType
	if error:
	self.message = error.get("Message", "error message undefined")
	self._response = response
	self.exit_code = response.get("StatusCode", 1) # we can assume this will be > 0
	error: dict[Any, Any] = response.get("Error") or {} # value from dict could be NoneType
	self.message = error.get("Message", "error message undefined")

Then, the __reduce__ method would return self.class, (self._response,)
