Error when extracting data from JSON webhook

Question

I am not able to access the data from the event in the python function

I am trying to get the name from the JSON

def handler(event, context):
     
    resp =  event
    user_name = resp['body']['user']['name']

but I get the following error

ERROR] TypeError: string indices must be integers
Traceback (most recent call last):
  File "/var/task/index.py", line 28, in handler
    user_name = resp['body']['user']['name']

maybe resp is already the body. try using resp['repository']['name'] and tell me the result. — alexzander

It seems that resp is of string type. load your response in JSON before accessing it.

import json
resp = json.loads(resp)

I am getting a Type Error for the json.loads(resp) ``` TypeError: the JSON object must be str, bytes or bytearray, not dict ```

alexzander Over a year ago

use json.load

It say AttributeError: 'dict' object has no attribute 'read'. when I use resp = json.load(event)

If I use json.dumps() for the above error I get the same error as in the top of my question TypeError: string indices must be integers

@AbilashJayanandan find out the type of resp by using type(resp)

The below solution worked for me. The event body should be retrieved first

import json

def handler(event, context):
     resp =  json.loads(event["body"])
     user_name = event['user']['name']
