Error de integración del servicio de notificación de inserción de AWS

Question

Estoy tratando de integrar notificaciones de Amazon Push a mi aplicación de iPhone. Seguí el tutorial proporcionado aquí correctamente.

Recibo este error al crear la plataforma EndPoint. (Parece un problema de permiso con el grupo de identidades ???)

CognitoIdentityCredentials is not authorized to perform: SNS:CreatePlatformEndpoint

Answer 1

El problema estaba en las configuraciones AWS SNS. Necesitamos agregar "SNS: CreatePlatformEndpoint" a la política para los roles Auth y Unuth

Answer 2

Puede agregar AmazonSNSFullAccess en Roles -> attach policy .
