When searching about this error ("Record not correctly loaded"), just find a similar mistake saying: "Uncaught Record not correctly loaded". I'ts the same? In the source code only encounter this error in the file data.js:

if (self.debug_mode) {
     if (_.include(records, undefined)) {
          throw "Record not correctly loaded";
     }
}

The strange thing is that this error occurs when I'm not in debug mode. (About this, I have found that debug_mode is set to true).

Is it possible to be a connectivity issue?

Regards!
