Error Sending FCM v1 Notification: "The notification has no target applications"
I'm using Google Firebase Cloud Messaging (FCM) v1 API to send notifications. I have configured my project with the following details:
Private Key Client Email Project ID
Response : { "message": "Error sending notification: The notification has no target applications. The notification format is gcm. Review the credentials specified in the notification hub description and the notification format.. TrackingId:5da2a253-53eb-4416-9655-80da98ea8a0b,TimeStamp:1/8/2025 8:01:16 AM +00:00" }
I am trying to send a notification to an Android device using the Firebase Cloud Messaging (FCM) v1 API. Despite configuring the private key, client email, and project ID correctly, I receive an error stating, "The notification has no target applications." I want to ensure that the notification reaches any Android device successfully. How can I resolve this issue and make sure the notification is sent to the intended devices?
