The variable 'HttpEvent<name[]>' cannot be assigned to the variable 'name[]' because their types are not compatible

This is the code I have written:

export interface act {
  id: number;
  name: string;
}
public list!: act[];
getAll(token:any): void{
  this.http.get<act[]>('http://localhost:4200/test', token)
  .subscribe(
    (val) =>
      this.list = val
  );
}

However, when I try to assign this.list = val, I encounter the following error:

Type 'HttpEvent < act[] >' is not assignable to type 'act[]'. Type 'HttpSentEvent' is missing the following properties from type 'act[]': length, pop, push, concat, and 16 more.

I have tried searching on Google and reading through Stack Overflow, but unfortunately, I have not been able to find a solution. While similar questions exist, they either remain unsolved or are not relevant to my specific issue.

I would greatly appreciate your assistance. Thank you in advance.

When attempting to send a request body, it's important to note that GET requests do not have a body. The second parameter in HttpClient.get() does not refer to the body, but rather to a set of options that impact what the method returns.

For sending data, consider using POST or PUT instead of GET.

Additionally, steer clear of utilizing the any type for improved readability and error handling. Using a properly defined interface would lead to more precise error messages from the compiler.
