FCM Android Notification sound issue - php

Question

I am trying to send notification using php to Android Application, and which is working fine without sound. I am receiving the notification both foreground and background as expected.
Here is the PHP code,
<?php
$token = $_GET['token'];
$action = $_GET['action'];
$msgTitle = $_GET['msgTitle'];
$msgDescription = $_GET['msgDescription'];
$notificationTitle = $_GET['notificationTitle'];
require './google-api-php-client-2.2.2/vendor/autoload.php';
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setAuthConfig('./testPrjoectAPP-firebase-adminsdk-9hn21-22c1b3f426.json');
$client->addScope('https://www.googleapis.com/auth/firebase.messaging');
$httpClient = $client->authorize();
$project = "testPrjoectAPP";
$message = [
"message" => [
"notification" => [
"body" => "Message FCM",
"title" => $notificationTitle
],
"token" => $token,
"data" => [
"action" => $action,
"msgTitle" => $msgTitle,
"msgDescription" => $msgDescription
]
]
];
$response = $httpClient->post("https://fcm.googleapis.com/v1/projects/{$project}/messages:send", ['json' => $message]);
echo$response->getReasonPhrase(); // OK
?>
But when I add sound parameter to notification payload and execute php I am getting Bad Request error from php.
.
$message = [
"message" => [
"notification" => [
"body" => "Message FCM",
"title" => $notificationTitle,
"sound" => "default"
],
// Send with token is not working
"token" => $token,
"data" => [
"action" => $action,
"msgTitle" => $msgTitle,
"msgDescription" => $msgDescription
]
]
];
Edit
Here is the error message I got while printing with
data: "{\n \"error\": {\n \"code\": 400,\n \"message\": \"Invalid JSON payload received. Unknown name \\\"sound\\\" at 'message.notification': Cannot find field.\",\n \"status\": \"INVALID_ARGUMENT\",\n \"details\": [\n {\n \"#type\": \"type.googleapis.com/google.rpc.BadRequest\",\n \"fieldViolations\": [\n {\n \"field\": \"message.notification\",\n \"description\": \"Invalid JSON payload received. Unknown name \\\"sound\\\" at 'message.notification': Cannot find field.\"\n }\n ]\n }\n ]\n }\n}\n"

As per my comment, You have to use your JSON like following way.
Solution:
The appearance of message in your JSON indicates you are using the HTTP v1 API. The documentation you linked is for the legacy API.
The HTTP v1 API JSON to send a notification with sound for Android and iOS devices should be:
{
"message":{
"token":"your-token-value",
"notification":{
"title":"Test",
"body":"Test message from server"
},
"android":{
"notification":{
"sound":"default"
}
},
"apns":{
"payload":{
"sound":"default"
}
}
}
}
Reference Link is: Unable to add sound to notification payload
Thank you.

Try this:
{
"message":{
"token":"your-token-value",
"notification":{
"title":"Test",
"body":"Test message from server"
},
"android":{
"notification":{
"sound":"default"
}
},
"apns":{
"payload":{
"sound":"default"
}
}
}
}
