botocore.client.Organizations.list_children does not return OUs

[TheHenrick]

Describe the bug

botocore.client.Organizations.list_children is inconsistent with aws cli.

import boto3

session = boto3.Session(profile_name='master-account-read-role')
organizations = session.client('organizations')

root_id = organizations.list_roots()["Roots"][0]["Id"]
ous = organizations.list_children(ParentId=root_id, ChildType="ORGANIZATIONAL_UNIT")["Children"]

print(len(ous))

0

root_id=$(aws --profile master-account-read-role organizations list-roots --query 'Roots[0].Id' --output text)
aws --profile master-account-read-role organizations list-children --parent-id $root_id --child-type ORGANIZATIONAL_UNIT --query 'Children[*].Id' --output text | wc -w

16

Expected Behavior

I expect boto3 to return all Organizational Units nested under a root account or Organizational Unit when using botocore.client.Organizations.list_children.

Current Behavior

boto3 does not return any Children OUs
