What's wrong with “$in” in mongoose

Question

Good day to everyone. I have a strange error working with mongoose

module.js:437

  var compiledWrapper = runInThisContext(wrapper, filename, tru

                        ^

SyntaxError: Unexpected token .

    at Module._compile (module.js:437:25)

    at Object.Module._extensions..js (module.js:467:10)

    at Module.load (module.js:356:32)

    at Function.Module._load (module.js:312:12)

    at Module.require (module.js:362:17)

    at require (module.js:378:17)

    at Object.<anonymous> (E:\Dropbox\Dropbox\FCP\server.js

    at Module._compile (module.js:449:26)

    at Object.Module._extensions..js (module.js:467:10)

    at Module.load (module.js:356:32)

I guess it's gone from

dbQueries.remove({_id: {$in: {req.body.data}}, authorId: req.user._id}, function onRemoveSomething(err){

            if(err) {

                res.json({epicFail: 'ERR_RestrictedAccess'});

                return; 

            }

        });

So, I have no idea what is wrong.

Answer 1

The $in takes an array, not an invalidly formatted javascript object

{_id: {$in: [req.body.data]}

or if req.body.data is already an array, omit the wrapping [ ]
