Type error : list indices must be integers or slices, not st

I am using django restframework to send a json like this :

[

{
  "email" : "[email protected]",
  "email" : "[email protected]",
   "meeting_date":"2021-06-29",
   "time_zone" : "Asia/Tehran"
}
]

and in views.py i need to get two fields like this:

serializer = EmailsListSerializer(data=request.data, many=True)
meeting_date = serializer.data['meeting_date']
meeting_timezone = serializer.data['time_zone']

but i got this error and don't know how to solve it :

 TypeError at /user/prefertimes/

list indices must be integers or slices, not str
  /home/admin1/envs/myvenv/lib/python3.8/site-packages/django/core/handlers/exception.py, line 47, in inner

                    response = get_response(request)

serializer = EmailsListSerializer(data=request.data, many=True)

Here you're providing many=True, which means that serializer.data is a list of dictionaries rather than a single dictionary. So, you need to access the the dictionary data like this:

meeting_date = serializer.data[0]['meeting_date']
meeting_timezone = serializer.data[0]['time_zone']

Alternatively, if you're always sending just one dictionary in your list in the json, you can omit many=True

serializer = EmailsListSerializer(data=request.data)

and send a dictionary instead of a list of dictionaries.

{
    "email" : "[email protected]",
    "email" : "[email protected]",
    "meeting_date":"2021-06-29",
    "time_zone" : "Asia/Tehran"
}
