Ember Data

Hi, I have a jsonapi:

1050×384 58.5 KB
In my member model:
1050×146 23.6 KB
it’s reflexive relationship I expect that the direct_reporting_employees is mapping to directReportingEmployees but I got: Uncaught TypeError: Cannot read property ‘_relationships’ of undefined it means in var relationship = this._internalModel._relationships.get(key); the this._internalModel is undefined anyone has experience with this problem? I did search but nothing work Thanks
