I am always getting the following error message:
/home/ccuser/workspace/learn-javascript-objects-meal-maker/app.js:39
** this._courses[courseName].push(dish);**
^
TypeError: Cannot read property ‘push’ of undefined

I read a previous topic about the same problem and I went through my code and corrected everything based on that, but I still get the error message above.
Can you help me what the probelem could be, please?
Thank you in advance!
