AWS cognito: Fix JSON syntax in pre token generation Lambda examples

Service: cognito · 2026-10-01 · Documentation low

File: cognito/latest/developerguide/user-pool-lambda-pre-token-generation.md

Summary

Removes trailing commas in the sample JSON payloads (preferredRole and cognito:user_status lines) so the examples are valid JSON.

Security assessment

The diff only corrects JSON syntax (trailing commas) in example payloads for the pre token generation Lambda trigger; it is a formatting fix with no security implications.

Evidence

+            "preferredRole": "arn:aws:iam::123456789012:role/new_role"
