I had the same issue, and the solution was to set the Service Name field in Postman AWS Signature settings used to sign the AWS Signature V4 auth header to iotdevicegateway as per the docs here: https://boto3.amazonaws.com/v1/文档/api/latest/reference/services/iot-data.html#IoTDataPlane.Client.get_thing_shadow
