I have a function in Firebase Functions service that send any FCM. I would to use admin.messaging().send() function, like this reference guide, but I got this error while function is triggered, not during deploy:
TypeError: admin.messaging(...).send is not a function

I can see this error in Functions->Log inside Firebase console.
That's my function code:
exports.sendChatNotification = functions.database.ref('/messages').onCreate(event => {
var message = {
data: {
title: 'title',
body: 'body',
},
apns: {
header: {
'apns-priority': '10',
'apns-expiration':'0'
},
payload: {
aps: {
sound: 'default',
'content-available':'1'
}
}
},
android: {
ttl: 60*1000,
priority: 'high'
},
topic: 'mytopic'
};
return admin.messaging().send(message);
});
If I use admin.messaging().sendToTopic() and (changing the message structure) it works fine. It seems Firebase doesn't support its own API.
I deploy this using Firebase tools, with command line "firebase deploy".
I have updated firebase-tools and firebase-functions and firebase-admin in my functions project.
