I have an oncreate function that doesn't seem to fire when I create data in my realtime database. I understand onCreate is used when new data is created in the Realtime Database. See code below.
What am I doing wrong?
exports.getNewReport =
functions.database.ref('/Hotel_Complaints/Users/{usersId}/')
.onCreate((snapshot, context) => {
// Grab the current value of what was written to the Realtime Database.
var user_id = context.params.usersId;
console.log(user_id);
// Grab the current value of what was written to the Realtime Database.
var eventSnapshot = snapshot.val();
var device_token = admin.database().ref('/Hotel_Staff/'+user_id+'/device_token').once('value');
return device_token.then(result => {
var token_id = result.val();
console.log(token_id);
var str = eventSnapshot.issue_description;
var payload = {
notification: {
title: "New complaint",
body: "New complaint for your department",
}
};
// Send a message to devices subscribed to the provided topic.
return admin.messaging().sendToDevice(token_id, payload).then(function (response) {
// See the MessagingTopicResponse reference documentation for the
// contents of response.
console.log("Successfully sent message:", response);
return;
})
.catch(function (error) {
console.log("Error sending message:", error);
});
});
});

By slightly adapting your promises chaining, it should do the trick, see below:
exports.getNewReport = functions.database.ref('/Hotel_Complaints/Users/{usersId}/')
.onCreate((snapshot, context) => {
// Grab the current value of what was written to the Realtime Database.
var user_id = context.params.usersId;
console.log(user_id);
// Grab the current value of what was written to the Realtime Database.
var eventSnapshot = snapshot.val();
var device_token = admin.database().ref('/Hotel_Staff/' + user_id + '/device_token').once('value');
return device_token
.then(result => {
var token_id = result.val();
console.log(token_id);
var str = eventSnapshot.issue_description;
var payload = {
notification: {
title: "New complaint",
body: "New complaint for your department"
}
};
// Send a message to devices subscribed to the provided topic.
return admin.messaging().sendToDevice(token_id, payload);
})
.then(response => {
// See the MessagingTopicResponse reference documentation for the
// contents of response.
console.log("Successfully sent message:", response);
return null;
})
.catch(error => {
console.log("Error sending message:", error);
return null
});
});
