Subscribe to topic?

[BStenfors9119]

Hello,

I am currently trying to implement cloud messaging using topics.

I can successfully subscribe and receive messages but my problem arises when I send a message to a topic the device isn't subscribed to. The device still receives the message!!

Maybe it's how I am creating the topics?

I have tried the following:

React Native Client side:

appMessaging.subscribeToTopic(subscriptionTopic)
                            .then((resp) =>
                            {
                                console.log('subscribed');
                                console.log(resp);
                            });

NodeJS Server side:

let fcmInfo = req.body.fcm;
let subscribedResult = await fbAdmin.messaging().subscribeToTopic(fcmInfo.token.toString(), fcmInfo.topic.toString());

I am trying to have multiple topics so I am dynamically generating them like so:

topic = `game_request.${ID}`

Would the "." cause an issue possibly?

TIA,
Bryan
