SNS with GMC V1 payload error

The error message "Notification body is invalid" typically occurs when the payload you're sending is not properly formatted according to the Firebase Cloud Messaging (FCM) protocol.

Here's the correct format for sending a notification to FCM via AWS SNS:

{
  "GCM": "{\"notification\":{\"body\":\"This is a notification message for FCM!\",\"title\":\"FCM Message\"}}"
}

If you want to send data payload instead of a notification, you can use the following format:

{
  "GCM": "{\"data\":{\"message\":\"This is a data message for FCM!\"}}"
}

Test the setup

1. Go to SNS console and open the platform application.
2. Select the endpoint and choose “Publish message”.
3. Select “Custom payload for each delivery protocol” and add the above message body.

Hi, thanks for the response, yes with this payload response ok but the push not delivered and the log sends "EventType":"DeliveryFailure","FailureMessage":"Notification body is invalid","FailureType":"InvalidNotification".

I created a new plattorm and with same json works fine, i think is for the migration to new FCM. The problem is all token register in the old platform.
