How to read object in subscribe (observable) -angular 6

0

I'm working on a project in angular 6 and i'm facing to a problem !
I want to read the content of an object which is in my observable like this:

this.myService.getOne().subscribe(e => 
 this.e = e;
 console.log(this.e);
 console.log(this.e.id); // result => undefined
);

I can see this.e which look like that:

"id":"1", "name":"myName", ...

But this.e.id is 'undefined', same thing when i write this.e['id'].

Did you have any idea ?

  By naming of' getAll(); I would assume you are getting and array so maybe e[0].id would do the trick. But until we see what your actual response you get this is just a guess.

I founded the problem, i had 2 things in more into my getOne() method:

I changed the method from

getOne(): Observable<myObject> ...

to

getOne() ...

I changed the return from

this.get<myObject>(url, httpOptions); //httpOptions contained headers and response type 'text' as 'json' 

to

this.get<myObject>(url);

Now its functional, thank you for your help ! :)
