Deleting data mongodb

When i'm deleting one collection in my MongoDB, i'm receiving this output:

{ result: 
   { ok: 1,
     n: 1,
     lastOp: Timestamp { _bsontype: 'Timestamp', low_: 1, high_: 1448429280 },
     electionId: 562020eaa64d1ba4e7af6f2a },
  connection: 
   EventEmitter {
     domain: null,
     _events: 
      { close: [Object],
        error: [Object],
        timeout: [Object],
        parseError: [Object],
        connect: [Function] },
     _eventsCount: 5,
     _maxListeners: undefined,
     options: 
      { socketOptions: {},
        auto_reconnect: true,
        host: 'ds053698.mongolab.com',
        port: 53698,
        cursorFactory: [Object],
        reconnect: true,
        emitError: true,
        size: 5,
        disconnectHandler: [Object],
        bson: {},
        messageHandler: [Function],
        wireProtocolHandler: {} },
     id: 3,
     logger: { className: 'Connection' },

     queue: [],
     connection: 
      Socket {
        _connecting: false,
        _hadError: false,
        _handle: [Object],
        _parent: null,
        _host: 'ds053698.mongolab.com',
        _readableState: [Object],
        readable: true,
        domain: null,
        _events: [Object],
        _eventsCount: 8,
        _maxListeners: undefined,
        _writableState: [Object],
        writable: true,
        allowHalfOpen: false,
        destroyed: false,
        bytesRead: 509,
        _bytesDispatched: 682,
        _sockname: null,
        _pendingData: null,
        _pendingEncoding: '',
        _idleNext: null,
        _idlePrev: null,
        _idleTimeout: -1,
        read: [Function],
        _consuming: true },
     writeStream: null,
     buffer: null,
     sizeOfMessage: 0,
     bytesRead: 0,
     stubBuffer: null } }

And ember is complaining about it. When i delete, the delete will happen.. but will also pop up this error:

TypeError: Cannot read property 'replace' of undefined
    at Object.func (ember.debug.js:39371)
    at Object.Cache.get (ember.debug.js:13297)
    at decamelize (ember.debug.js:39408)
    at Object.func (ember.debug.js:39328)

    at ember$data$lib$serializers$json$serializer$$default.extend._normalizeDocumentHelper (json-api-serializer.js:118)

And the return response is:

{"data":{"ok":1,"n":1,"lastOp":"6220957784033198081","electionId":"562020eaa64d1ba4e7af6f2a"}}

This is happening when i try to edit, too.

Thanks guys.
