Error and crash when receive a push in foreground

[jordanbisato]

Hi,

When i receive a push in foreground on android using the 3.3.1 released version (and with 3.3.1 version from m1g4 too https://github.com/hansemannn/titanium-firebase-cloud-messaging/pull/137) i receive an error:

[DEBUG] FirebaseMsgService: Message Notification Body: TEST
[ERROR] V8Exception: Exception occurred at undefined:1050: Uncaught Error: Attempt to get length of null array
[DEBUG] AndroidRuntime: Shutting down VM

I put some logs into it to get the exactly location of error and it occours on CloudMessagingModule.java inside onMessageReceived in this line: fireEvent("didReceiveMessage", data);

It's possible give a look on it? Thanks!

Using an Xiaomi Mi 9T with Android 10 to test. SDK 11.0.0.GA

can you say what is null? Since that part is in a try/catch it should end up in message exception if that line fails. The V8Exception is thrown by the SDK. Not sure at the moment where it tries to get the length of.

[jordanbisato]

No, i can't discover what is null. I only know it's between the fireEvent on https://github.com/hansemannn/titanium-firebase-cloud-messaging/blob/main/android/src/firebase/cloudmessaging/CloudMessagingModule.java#L239 and before the function of listener in my code.

fcm.addEventListener("didReceiveMessage", onMessage);
function onMessage(e) {
        // Fired for all kind of notifications (foreground, background & closed)
        Ti.API.debug("######### Got message: " + JSON.stringify(e));
        Alloy.Globals.fcm.lastData = e.data;
        Alloy.Globals.fcm.lastData.inBackground = e.inBackground;
    }

[m1ga]

If you can reproduce it please add a Log.i("---", data.toString()); before to see if the data is filled. And Log.i("---", "Message: " + message); before 238. Perhaps its the message that can't be parsed into a KrollDict. That lines hasn't been touched for 4 years (besides the linting in the last version)

[hansemannn]

Maybe it's related to the "data" changes we merged recently? It would be interesting to know if an earlier version works. But yeah, the debug logs will help!

[m1ga]

could be but only if it is a data notification. But since Message Notification Body is called it should be a normal notifiaction and not go into that branch. But will check that

[jordanbisato]

Huum, i noted something: i was sending a Data notification, but it enter in the if of the message notification. In background it works well, but on foreground it crash.

[m1ga]

what are you using to send the notification? And can you show the content?

[jordanbisato]

I'm using the firebase console to send the push. The content of push (in background):

Last data: {"google.original_priority":"high","gcm.n.analytics_data_google.c.a.c_l":"TESTE","google.sent_time":"1661886749988","telaPush":"/aporte/aporte","google.delivered_priority":"high","google.message_id":"0:1661886749998202%452c09d0452c09d0","collapse_key":"br.com.cvpb","gcm.n.analytics_data_google.c.a.ts":"1661886749","gcm.n.analytics_data_google.c.a.c_id":"7234120883046604539","inBackground":true,"google.ttl":"2419200","from":"869891314489","gcm.n.analytics_data_from":"869891314489","gcm.n.analytics_data_google.c.a.e":"1","gcm.n.analytics_data_google.c.a.udt":"0"}

[jordanbisato]

And here the log of module on crash:

[DEBUG] FirebaseMsgService: Message Notification Body: TESTE

[DEBUG] FirebaseCloudMessaging: (Firebase-Messaging-Intent-Handle) [61897,69177] onMessageReceived

[ERROR] V8Exception: Exception occurred at undefined:1052: Uncaught Error: Attempt to get length of null array

[m1ga]

so like this ? That works fine here.

I wonder if it is realted to: https://github.com/hansemannn/titanium-firebase-cloud-messaging/pull/137#issuecomment-1144844079 since you have some other analytics data in your notification.

[jordanbisato]

I put a log before this line: https://github.com/hansemannn/titanium-firebase-cloud-messaging/blob/main/android/src/firebase/cloudmessaging/TiFirebaseMessagingService.java#L74

And send a push with data and one without data.

The result:

With data:

[DEBUG]  FirebaseMsgService: remoteMessage.getData(): {telaPush=/aporte/aporte}

[DEBUG]  FirebaseMsgService: remoteMessage.getNotification(): com.google.firebase.messaging.RemoteMessage$Notification@75a163e

[DEBUG]  FirebaseMsgService: Message Notification Body: TESTE

Without data:

[DEBUG]  FirebaseMsgService: remoteMessage.getData(): {}

[DEBUG]  FirebaseMsgService: remoteMessage.getNotification(): com.google.firebase.messaging.RemoteMessage$Notification@a9fa087

[DEBUG]  FirebaseMsgService: Message Notification Body: TESTE

Both entered in the if.

I think we need verify if data is truly, because remoteMessage.getNotification() isn't null in both cases.

[m1ga]

The notification from Firebase is a mixed notification, so it has a notification block and a data part.

So this is my Firebase console push:

Message Notification Body: asdf

Message: {messageType=null, data={"asdf":"234"}, messageId=0:1661888246119579%ac3e80e4ac3e80e4, from=47582397024, to=null, title=asdf, body=asdf, ttl=2419200, sendTime=1661888190127}

KrollDict: {"message":{"messageType":null,"data":{"asdf":"234"},"messageId":"0:1661888246119579%ac3e80e4ac3e80e4","from":"47582397024","to":null,"title":"asdf","body":"asdf","ttl":2419200,"sendTime":1661888190127}}

and this is a data notification using PHP:

Data message: {telaPush=/aporte/aporte, id=1, type=noti/data: data part, badge=5, channelId=my_channel1}

Messge: {messageType=null, data={"badge":"5","id":"1","type":"noti\/data: data part","telaPush":"\/aporte\/aporte","channelId":"my_channel1"}, messageId=0:1661888210990602%ac3e80e4f9fd7ecd, from=47582397024, to=null, ttl=2419200, sendTime=1661888210973}

KrollDict: {"message":{"messageType":null,"data":{"badge":"5","id":"1","type":"noti\/data: data part","telaPush":"\/aporte\/aporte","channelId":"my_channel1"},"messageId":"0:1661888210990602%ac3e80e4f9fd7ecd","from":"47582397024","to":null,"ttl":2419200,"sendTime":1661888210973}}

Both cases don't crash for me and all of them have the data node.

I've found the issue :rofl: your log: Ti.API.debug("######### Got message: " + JSON.stringify(e));

remove that :wink:

[jordanbisato]

OMG. THAT'S IT!!! Hahahaha Worked now! Thanks again @m1ga

[m1ga]

But why didn't it show you that log but only the V8 part :thinking:

[jordanbisato]

And how i can get the data in a foreground notification? Because JSON.stringify(e) crash, and if i log the e.data or e.inBackground, both are undefined.

[m1ga]

I use

if (OS_ANDROID) {
        console.log("Got message: " + JSON.stringify(e.message));
        alert("Got message: " + JSON.stringify(e.message.data));
    } else {
        var data = JSON.parse(e.data || '');
        console.log("Got message: " + JSON.stringify(data));
        alert("Got message: " + JSON.stringify(data));
    }

in my test app

[jordanbisato]

It worked like a charm! You're the man. Thank you.
