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

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 ?

For the e, i see the entire object in the console but for e.id, i see 'undefined' whereas i can see 'id' into e

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 ! :)
