Nodejs return Asynchronously result as an array - node.js

Question

in my server application i have some method such as:
insert message when user joined to application(insertUserJoinedMessageAndSendMessage)
get unique id of owner mobile numbers (getOwnerPhoneNumberUniqueIds)
print generated data
in this solution i have:
insertUserJoinedMessageAndSendMessage(userPhoneNumbers, assignedUserId.id)
.then(function (t) {
return getOwnerPhoneNumberUniqueIds(userPhoneNumbers);
})
.then(function (result) {
log.info(result);
})
.catch(function (error) {
log.info(error);
});
methods, insertUserJoinedMessageAndSendMessage method work fine without any problem, i want to get generated data on nested Promise as getUserId() from getOwnerPhoneNumberUniqueIds() Promise function, but i can't print data on this part of code as log.info(result); because i can't return array from getOwnerPhoneNumberUniqueIds()
function insertUserJoinedMessageAndSendMessage(userPhoneNumbers, ownerUserId) {
return new Promise(function (resolve, reject) {
let query = "INSERT INTO `userJoinedMobileNumbers` (`id`, `userId`, `nameAndFamily`, `mobileNumber`, `created_at`, `updated_at`) VALUES ";
userPhoneNumbers.map(function (curr) {
query += "(NULL, " + ownerUserId + ", " + curr.contactName + ", " + curr.contactPhone + ", CURRENT_TIMESTAMP, CURRENT_TIMESTAMP),";
});
query = query.substr(0, query.length - 1) + ";";
connection.query(query, function (err, results) {
if (err) return reject(err);
resolve(true);
});
});
}
function getOwnerPhoneNumberUniqueIds(data) {
return Promise.all(data.map(function (curr) {
return getUserId(curr.contactPhone)
.then(function (data) {
log.info("1) " + data);
return {id: data};
});
})).then(function (accountNumbers) {
log.info("2) " + accountNumbers);
return accountNumbers
}).catch(function (err) {
console.log(err);
});
}
function getUserId(contactPhone) {
return new Promise(function (resolve, reject) {
var query = "SELECT id FROM sendMessageUserJoined WHERE `phoneNumber` ='" + contactPhone + "'";
connection.query(query, function (err, results) {
if (err) return reject(err);
if (results.length > 0) {
log.info("0) " + results[0].id);
resolve(results[0].id);
}
});
});
}
in log.info("0) " + results[0].id); i get result of sql command and that return id successful to getOwnerPhoneNumberUniqueIds() and i can print result with this part of code as log.info("1) " + data);, now how can i return that on:
.then(function (accountNumbers) {
log.info("2) " + accountNumbers);
return accountNumbers
})
log.info("2) " + accountNumbers);
dont print result which returned by return {id: data};

The problem is in getUserId.
In some cases you wouldn't resolve or reject the promise. So your Promise.all returned promise maintained pending.
function getUserId(contactPhone) {
return new Promise(function (resolve, reject) {
var query = "SELECT id FROM sendMessageUserJoined WHERE `phoneNumber` ='" + contactPhone + "'";
connection.query(query, function (err, results) {
if (err) return reject(err);
if (results.length > 0) {
log.info("0) " + results[0].id);
resolve(results[0].id);
}
else { //this part is missing
resolve(); //or reject
}
});
});
}
