I have googled both the message and error and it seems the issue I keep finding is not what I am dealing with.
I am an angular noob and feel I am finally close to getting my service wired up.
I am getting the above error on my component
it will squawk at the this.posts below.
getPosts() {
this.postsService.get()
.subscribe((data: Post) => this.posts = data);};
and my service in case theres an issue there.
public get(): Observable<Post> {
return this.http
.get<Post>(this.accessPointUrl);}
Someone save my morning please!

Add pipe operator in your service - that will helpthis.http.get<Post>(this.accessPointUrl).pipe();

In that case, change the type back toObservable<Post>, and remove thesubscribe, so it becomesthis.posts = this.postsService.get()

When you say it's logging undefined, where are you logging? Is it inside the subscribe function, or outside? Because the code is asynchronous, so if you try to log it outside of the subscribe function it will never work

There are two options you either change your posts variable to Post
or you dont subscribe to the get() method of your service and directly assign it to your observable variable like this:
this.posts = this.postsService.get();
