types.GenericAlias' object is not iterable

This error occurs when trying to iterate over an object of type `types.GenericAlias`, which is not iterable.
`types.GenericAlias` is a class that represents a generic type in Python, such as a list or dict with specified types for its elements or keys/values. For example, `List[int]` is a `GenericAlias` representing a list of integers.
To fix this error, you need to ensure that you are iterating over an iterable object, such as a list or tuple, rather than a `GenericAlias`. If you are unsure if an object is iterable, you can check if it has a `__iter__` method:
```python
if hasattr(my_object, '__iter__'):
# object is iterable
for item in my_object:
# do something with item
else:
# object is not iterable
# handle error here
```
