C2W2 Lab1 batching Exercise 3 & 6 potential infinite loop

My exercises 3 & 6 ran extremely long and I am not sure how to debug. Exercise 6 I can ran the scripts but the playlist_items_.json never got created and I can see in the terminal that request was constantly made.

My exercise 3 code was as follows. I have to manually stoped it otherwise it is an infinite loop. Can anyone shed some light on how to solve the infinite loop?(I have little experience working with APIs)

def paginated_with_next_featured_playlists(endpoint_request: Callable, url: str, access_token: str) → list:
“”"Manages pagination for API requests done with the endpoint_request callable

Args:
    endpoint_request (Callable): Function that performs API request
    url (str): Base URL for the request
    access_token (str): Access token

Returns:
    list: Responses stored in a list
"""
responses = []
    
next_page = url

kwargs = {
        "url": url,
        "access_token": access_token,
        "next": ""
    }

#ctn =0 
while next_page :

    print(f"Executed request with URL: {response.get('playlists').get('href')}.")
            
return responses

Hello @toliu
The test cell for exercise 3 uses the get_featured_playlists method, which we fill in in exercise 1. Therefore, please check for your code for exercise 1 as well and make sure that it is working properly.
