Running a native image on GCP (Cloud Run) throws error 400

Commencez par les déclarations de dépendances de Firebase Admin et par le client Firebase Cloud Messaging exécuté en tant qu’image native sur Cloud Run, en comparant le comportement signalé de JVM et de native-image. Reproduisez la réponse 400 avec l’exclusion de grpc-netty-shaded et la substitution de grpc-okhttp, puis déterminez si le problème se situe dans la construction de la requête ou dans la configuration de native-image. La tâche est terminée lorsqu’une configuration prise en charge ou un diagnostic minimal reproductible est documenté.

Hi,

Compiling to native this dependency:

<dependency>
      <groupId>com.google.firebase</groupId>
      <artifactId>firebase-admin</artifactId>
      <version>9.2.0</version>
</dependency>

makes the build fail because grpc-netty-shaded, however with this alternative we can compile:

<!-- FCM -->
    <dependency>
      <groupId>com.google.firebase</groupId>
      <artifactId>firebase-admin</artifactId>
      <version>9.2.0</version>
      <exclusions>
        <exclusion>
          <groupId>io.grpc</groupId>
          <artifactId>grpc-netty-shaded</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

    <!--Using OkHttp over netty because the shaded netty included in grpc does not work with native image-->
    <dependency>
      <groupId>io.grpc</groupId>
      <artifactId>grpc-okhttp</artifactId>
      <version>1.51.1</version>
    </dependency>

The problem is that FCM client always responds with error 400:

Exception in thread "main" com.google.firebase.messaging.FirebaseMessagingException: Unexpected HTTP response with status: 400
{
  "error": {
    "code": 400,
    "message": "Recipient of the message is not set.",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.BadRequest",
        "fieldViolations": [
          {
            "field": "message",
            "description": "Recipient of the message is not set."
          }
        ]
      },
      {
        "@type": "type.googleapis.com/google.firebase.fcm.v1.FcmError",
        "errorCode": "INVALID_ARGUMENT"
      }
    ]
  }
}

Running on JVM works fine.
There is a issue with same problem: https://github.com/GoogleCloudPlatform/native-image-support-java/issues/116 for the old google native support libraries. Their workarounds didn't work for me.

Are there any know solutions?
Thanks
