firebase cloud messaging Request contains an invalid argument

I am getting error while sending message using Firebase cloud messaging admin API.

Error message is below

Caused by: com.google.api.client.http.HttpResponseException: 400 Bad Request { "error": { "code": 400, "message": "Request contains an invalid argument.", "errors": [ { "message": "Request contains an invalid argument.", "domain": "global", "reason": "badRequest" } ], "status": "INVALID_ARGUMENT" } }

Let me put my admin configuration here..

FileInputStream serviceAccount = new FileInputStream("My service accout file.json");

FirebaseOptions options = new FirebaseOptions.Builder().setCredentials(GoogleCredentials.fromStream(serviceAccount))
                    .setDatabaseUrl("https://deliveryeat-1aa42.firebaseio.com").build();

FirebaseApp.initializeApp(options);

Message sending code is below

// This registration token comes from the client FCM SDKs.
String registrationToken = "YOUR_REGISTRATION_TOKEN";

// See documentation on defining a message payload.
Message message = Message.builder().putData("score", "850").putData("time", "2:45").setToken(registrationToken).build();

// Send a message to the device corresponding to the provided
// registration token.
String response = FirebaseMessaging.getInstance().sendAsync(message).get();
// Response is a message ID string.
System.out.println("Successfully sent message: " + response);

maven dependencies that i am using is following

<dependency>
    <groupId>com.google.firebase</groupId>
    <artifactId>firebase-admin</artifactId>
    <version>5.9.0</version>
</dependency>

So can anyone help me in this? What am I doing wrong?

This error also occurs when trying to send a push-notification to an iOS simulator device.

In my case the problem was in Condition part. I used invalid characters.

For example wrong: 03:00' in topics

I received this error trying to set the 'content_available' flag to true (which is what the docs say to do: https://firebase.google.com/docs/cloud-messaging/http-server-ref).

Turns out you need it to be 'content-available' instead.

I had my project name uppercased in the URL (strange, because my project name is actually uppercased)

Yet another cause of this is that your message is too large:

Notification messages can contain an optional data payload. Maximum payload for both message types is 4KB, except when sending messages from the Firebase console, which enforces a 1024 character limit.

In my case, the problem was that certain keys are not allowed in a notification data payload. Specifically, the key 'from' is forbidden.

One possible cause for this is that the client and server are connected to different firebase projects. Project name appears in the google-services.json file on the client and in the credentials json on the server.

I suspect that your registrationToken has an invalid format. It should be 152 characters.

To confirm that, try building your message with setTopic("test") instead of setToken(registrationToken).
