$push to an array in MongoDB with mongoose doesn't work -


errmsg: 'the field \'weight\' must array of type int in document

my schema: 

weight: [{   type: number }]

and post request: 

app.post('/edit', function(req, res){     var update = {  $push: {"weight": req.body.weight}};     user.findoneandupdate(conditions, update, options, function (err)     {       if (err)       {           console.log(err);       }       else       {           console.log('yep');       }     }) });

if there multiple documents in collection match conditions, can update suitable 1 adding { weight: { $type: 4 } } conditions.

otherwise application's schema doesn't match data in database.
