Firebase Functions Gives Timeout On Client Side After 10s

I am using getHttpsCallable to call a cloud function on Android but the function returns with FirebaseFunctionsException: DEADLINE_EXCEEDED error if it takes more than 10 seconds. When I checked on firebase (Server side), it shows function completed (without any ERROR).

Note: This function works perfectly on iOS and fails on Android after 10 seconds

I tried this solution here as issue appears similar to this one but still fucntion fails if it takes more than 10s.

I am using latest dependencies in gradle,

dependencies {
    // 
    implementation 'com.google.firebase:firebase-functions:18.0.0'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    implementation 'com.google.firebase:firebase-auth:18.0.0'
    implementation 'com.google.firebase:firebase-storage:18.0.0'
}

Hers is my function,

HttpsCallableReference ref = mFunctions.getHttpsCallable("myFirebaseFunction");
ref.setTimeout(600, TimeUnit.SECONDS);
ref.call(Data)
    .addOnSuccessListener(new OnSuccessListener<HttpsCallableResult>() {
                @Override
                public void onSuccess(HttpsCallableResult httpsCallableResult) {
                    Gson jsonData = new Gson();
                    String json = jsonData.toJson(httpsCallableResult.getData());
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    e.printStackTrace();
                }
            });

Here is the stack-trace log,

Is there something that I am missing here? I would really appreciate any help.

This is a bug in the Android client library regarding the different types of timeouts available for OKHTTP. You can read about the fix here:
