boto3 Cognito idp list_users function can't show all attributes

[joeherro]

I'm using the following Python code to retrieve the users in a user pool (where MAX_NUMBER_RECORDS = 10, LIMIT = 5, REGION, PROFILE, and USER_POOL_ID are the corresponding AWS values from the account):

import boto3
import json

def convert_date_to_string(o):
if isinstance(o, datetime.datetime):
return str(o)

def get_cognito_user_pool_list(cognito_idp_client, next_pagination_token ='', Limit = LIMIT):
return cognito_idp_client.list_users(
UserPoolId = USER_POOL_ID,
Limit = Limit,
PaginationToken = next_pagination_token
) if next_pagination_token else cognito_idp_client.list_users(
UserPoolId = USER_POOL_ID,
Limit = Limit
)

session = boto3.Session(profile_name=PROFILE)
client = session.client('cognito-idp', REGION)

user_records = get_cognito_user_pool_list(
cognito_idp_client = client,
next_pagination_token = pagination_token,
Limit = LIMIT if LIMIT < MAX_NUMBER_RECORDS else MAX_NUMBER_RECORDS
)

json_formatted_str = json.dumps(user_records, indent=4, default=convert_date_to_string)
print('User records:' + json_formatted_str)

returns the following:

{
"Username": "!!!",
"Attributes": [
{
"Name": "sub",
"Value": "13a9643b-d7ee-4e3e-b9cd-d1960ba77819"
},
{
"Name": "email_verified",
"Value": "false"
},
{
"Name": "email",
"Value": "a@a"
}
],
"UserCreateDate": "2024-02-26 12:15:21.294000-06:00",
"UserLastModifiedDate": "2024-02-26 12:15:21.294000-06:00",
"Enabled": true,
"UserStatus": "UNCONFIRMED"
}

Does anyone have insight as to why the remaining attributes (name, preferred_username, etc.) do not appear?

Thanks.

This is resolved. The code actually works. The issue is that there are many empty fields in the user pool entries themselves. That's why nothing was showing up in the user_records. Thanks.
