How to impalement in code

Task: Delete Object With API

this must me a string not a object.
what should I do?

Hello, @Farhan007.

Could you please provide the code that you trying to call.
By mistake, I can say that you did not specify the Object ID in the function call.

Best Regards, Nikita.

// persons-list/persons-list.component.ts
import { Component, OnInit } from '@angular/core';
import { PersonsService } from '../persons.service';
selector: 'app-persons-list',
templateUrl: './persons-list.component.html',
styleUrls: ['./persons-list.component.css']
export class PersonsListComponent implements OnInit {
constructor(private personsService: PersonsService) {
ngOnInit() {
getpersons() {
  this.personsService.find().then((Object:any) =>{

deletePerson() {
  this.personsService.delete(Object).then( function (savedObject) {
    console.log( 'Object has been removed' );
  }).catch(function (error) {
    console.log( 'Error removing object ' + 
    throw error;

// persons.service.ts
import { Injectable } from '@angular/core';
import Backendless from 'backendless';

providedIn: 'root'
export class PersonsService {
public persons: Object[] = [];
find() {
 return Backendless.Data.of('Person').findFirst()

delete(Object: any){
  return Backendless.Data.of('Person').remove(Object)

Instead of ‘Object’ you need to pass the ‘objectId’ value of your object.
Like this:
Backendless.Data.of( "Person" ).remove('251E1D02-3448-4D56-91E3-A6A5F5F9996A')
