Im getting this error and i dont know how to solve it.
In a node js server, i'm using some .then() function on a promise and at the end i placed a .catch() function that for some reason is not recognized.
I have seen in many places in tutorials that this is how an error is handled.
I'm not using any external libraries.

The error :

 TypeError: promise.then(...).then(...).then(...).then(...).catch is not a function

This is my code:

exports.joinAlbum = function(req, res){





var promise = Album.findOne().where({'shortId': req.body.shortId}).exec(); // Returns a promise





promise.then(function(albumDoc){

    console.log('Then #1');



    .....



    }

    return albumDoc.save();  // Returns a promise

})







.then(function(albumDoc){

    console.log('Then #2');



    .....



    return User.findById(req.body.userId).exec(); // Returns a promise

})





.then(function(userDoc){

    console.log('Then #3');



     ........



    return userDoc.save();  // Returns a promise

})



//  Return a response

.then(function(savedUserDoc){

    console.log('Then #4');

    return res.status(200).json({success: true}); 

})



    //Error handler

.catch(function(err){

    console.log('Catch #1');

    console.log(err);

    res.status(200).json({success: false});

});

}

If .catch() is not the correct way to handle promise error, what do you suggest? Im trying to avoid using external libraries and prefer using native javascript

EDIT: solution

I added a npm module called blue-bird that helped me solve this.
