The json module is imported again here, but should be imported only once at the top of the file (after line 199). Remove this duplicate import statement.

The json module should be imported at the top of the file (after line 199, with the other imports) rather than inside the method. Import statements inside methods are considered poor practice in Python as they can impact readability and performance. The same applies to the duplicate import on line 251.
Move import json to line 200 (after from abc import ABC, abstractmethod) and remove the imports from lines 242 and 251.
