Saving 3 schema simultaneously in MongoDB - node.js

Question

I'm trying to save in 3 schema (User, UserDetail and Team) data in mongo DB simultaneously but I receive an error
(node:14432) UnhandledPromiseRejectionWarning: Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
Here's my code
self.createTeam = function (req, res) {
Logger.request(req);
Logger.requestBody(req);
bcrypt.hash(req.body.password, 10, function (err, hash) {
if (err) {
return res.status(500).json({
error: err
})
} else {
req.body.password = hash;
const team = new Teams({
_id: new mongoose.Types.ObjectId(),
domain: req.body.domain,
avatarOriginal: req.body.avatarOriginal,
avatar_180x180: req.body.avatar_180x180,
avatar_180x100: req.body.avatar_180x100,
name: req.body.name,
createdAt: Date.now(),
updatedAt: Date.now()
});
const user = new User({
_id: new mongoose.Types.ObjectId(),
username: req.body.username,
email: req.body.email,
password: hash,
createdAt: Date.now(),
updatedAt: Date.now()
});
const userDetail = new UserDetail({
_id: new mongoose.Types.ObjectId(),
user_id: user._id,
team_id: team._id,
firstName: req.body.firstName,
lastName: req.body.lastName,
createdAt: Date.now(),
updatedAt: Date.now()
})
team.save().then(function (result) {
return user.save();
}).then(function (result) {
return userDetail.save();
}, function (err) {
res.status(500).json({
error: err
});
}).then(function (user) {
Logger.response(req, user);
res.status(200).json({
success: 'New team and user has been created'
})
})
}
})
}
Please help thank you
