如何修复=> FormArray。找不到具有路径的控件

const control = this.myForm.get('myFormArray').at(index);

this.myFormArray.push(new FormControl());

this.myService.getData().subscribe(data => {
  data.forEach(item => {
    this.myFormArray.push(new FormControl(item));
  });
});

import { Component } from '@angular/core';
import { FormBuilder, FormArray, FormControl } from '@angular/forms';

@Component({
  selector: 'app-my-form',
  template: `
    <form [formGroup]="myForm">
      <div formArrayName="myFormArray">
        <div *ngFor="let control of myFormArray.controls; let i = index" [formGroupName]="i">
          <input formControlName="name" placeholder="Name">
        </div>
      </div>
    </form>
  `
})
export class MyFormComponent {
  myForm: FormGroup;

  constructor(private fb: FormBuilder) {
    this.myForm = this.fb.group({
      myFormArray: this.fb.array([])
    });
  }

  get myFormArray(): FormArray {
    return this.myForm.get('myFormArray') as FormArray;
  }

  addControl() {
    this.myFormArray.push(this.fb.control(''));
  }
}
