找不到路径控制

Question

我的反应性表单无法在其基础表单组中找到表单控件。

这是错误：

ERROR Error: Cannot find control with path: 'mailSettings -> sendReminder'

在ngOnInit()中，我通过初始化表单

private _initForm(): void {
  const mail: FormGroup = this._fb.group({
    sendReminder: [false, [Validators.required]],
    contacts: [this._fb.array([]), [Validators.required]]
  });
  const exposure: FormArray = this._fb.array([]);
  this.settingsForm = this._fb.group({
    photoUrl: [this.settings.photoUrl, []],
    isActive: [this.settings.isActive, [Validators.required]],
    idMdm: [this.settings.idMdm, [Validators.required]],
    idPms: [this.settings.idPms, [Validators.required]],
    name: [this.settings.name, [Validators.required]],
    functionalCurrency: [this.settings.functionalCurrency, [Validators.required]],
    mailSettings: [mail, []],
    exposures: [exposure, []]
  });
}

然后在组件HTML中通过以下方式引用

：

<form [formGroup]="settingsForm">
  <mat-vertical-stepper>
    <!-- company data -->
    <mat-step>
      <ng-template matStepLabel>Company Data</ng-template>
      <mat-slide-toggle color="primary" #enabled formControlName="isActive"></mat-slide-toggle> {{enabled.checked ? 'Enabled' : 'Disabled'}}<br><br>
      <mat-form-field class="name"><input matInput placeholder="Name" formControlName="name"></mat-form-field><br>
      <mat-form-field class="marginRight16px"><input matInput placeholder="Id PMS" formControlName="idPms"></mat-form-field>
      <mat-form-field class="marginRight16px"><input matInput placeholder="Id MDM" formControlName="idMdm"></mat-form-field>
      <mat-form-field class="marginRight16px"><input matInput placeholder="Functional Ccy" formControlName="functionalCurrency"></mat-form-field><br>
    </mat-step>
    <!-- contact info -->
    <mat-step>
      <ng-template matStepLabel>Contact Info</ng-template>
      <div formGroupName="mailSettings">
        <mat-slide-toggle color="primary" #reminder formControlName="sendReminder"></mat-slide-toggle> {{reminder.checked ? 'Send' : 'Do not send'}}<br><br>
      </div>
    </mat-step>
    <!-- exposure data -->
    <mat-step>
      <ng-template matStepLabel>Exposure</ng-template>
    </mat-step>
  </mat-vertical-stepper>
</form>

对我所缺少的东西有什么想法吗？任何帮助表示赞赏！
