In firebase project I have an array messages
containing a Map with the fields message
, timestamp
and type
. I’m trying to access these fields with the lastMessage: data.messages;
however the console.log
returns me as Undefined. Does anyone know any way to access these fields?
exports.onConversationCreated = functions.firestore.document('chat/{chatId}')
.onCreate((snapshot, context) => {
let data = snapshot.data();
let chatId = context.params.chatId;
if(data){
let members = data.members;
let lastMessage = data.messages;
for(let index = 0; index < members.length; index++){
let currentUserId = members[index];
let remainingUsersId = members.filter((u) => u != currentUserId);
console.log(lastMessage.message);
remainingUsersId.forEach((m) => {
return admin.firestore().collection('authUsers').doc(m).get().then( (_doc) => {
let userData = _doc.data();
if(userData) {
return admin.firestore().collection("authUsers")
.doc(currentUserId).collection('chat').doc(m).create({
"chatId": chatId,
"image": userData.photoUrl,
"name": userData.displayName,
"unseenCount": 0
});
}
return null;
}).catch(() => {return null});
})
}
}
return null;
});
