PreTokenGenerationTriggerEvent => claims_to_suppress : NoneType' object does not support item assignment

See original GitHub issue

What were you trying to accomplish? I’m currently trying to add some claims to suppress to the token in the event object. Working with manual way (without your lib).

Expected Behavior

No exception

Current Behavior

Exception

Possible Solution

Steps to Reproduce (for bugs)

def handler(event, context):
    event: PreTokenGenerationTriggerEvent = PreTokenGenerationTriggerEvent(event)
    user_pool_id = event.user_pool_id
    claims_override_details = event.response.claims_override_details
    claims_override_details.claims_to_suppress = ["Email"]

Environment

Powertools version used: 1.22.0
Packaging format (Layers, PyPi):
AWS Lambda function runtime: Python 3.9
Debugging logs

    "exception": "Traceback (most recent call last):\n  File \"/var/task/main.py\", line 130, in handler\n    claims_override_details.claims_to_suppress = []\n  File \"/var/task/package/aws_lambda_powertools/utilities/data_classes/cognito_user_pool_event.py\", line 487, in claims_to_suppress\n    self._data[\"claimsToSuppress\"] = value\nTypeError: 'NoneType' object does not support item assignment"
