TypeError: Cannot read property 'headers' of null! MEAN stack

i am making a simple ToDoApp with MEAN(Angular2) stack but im having a problem with the http.post request. Always when i run the post method the current JSON object gets inserted into the database but right after i get a error message and also my current server connection breaks down.

Insert method:

post method

The error in the console:

Console error

CORS is allowed on the backend side and i dont know what else to try. Any suggestions??

Also in my terminal in Visual Studio code i get an error which says: TypeError: Cannot read property 'headers' of null
