尝试更新同一组件中的输入值,但无法更新。出现如下错误

ERROR
Error: Cannot read properties of undefined (reading 'pop')

那么,如何解决这个问题呢?
table.component.ts:

export class TableComponent implements OnInit {
@Input() names: any;

constructor() {}

ngOnInit() {}

testFn() {
  this.names.pop('Test22');
  this.names = [...this.names];
  console.log(this.names);
}

}
