NgFor only supports binding to Iterables such as Arrays. i feel my code is correct anybodies help will be appreciated

my service.ts

  userdetails(activation_code):Observable<account_details[]>
 {
   return this.http.get<account_details[]>('http://127.0.0.1:8080/api/Home/account_details? 
   activationcode='+activation_code)

 } 

my component.ts

account: account_details[];
ngOnInit(): void {
this.Backend.userdetails(this.x).subscribe(data => {
this.account = data;
console.log(this.account);
});

My account_details.ts Cannot find a differ supporting object '[object Object]' of type 'object'. NgFor only supports binding to Iterables such as Arrays.

export interface account_details
{
 Account_number:number;
 Account_type: string;
 Activationcode: string;
 Balance: number;
 DOB: Date;
 Date_of_creation: Date;
 Email_address: string;
 ID: number;
 Loan: string;
