使用模型和formgroupdirective时找不到带有路径的控件

我的Angular 8应用程序使用了很多嵌套形式，为了尽量减少代码量，我设置了一个模型类来为我的反应形式定义结构。我的html页面上有一组嵌套的组件，应该可以创建一个表单来添加或更新数据。当尝试使用基于模型结构的现有数据填充表单时，我现在收到一条错误消息，例如（错误）：错误错误：找不到路径为“ info-> charName”的控件

在home.ts中，导入导出的类，并创建父窗体，如下所示：

this.CharGenMagusForm = this.fb.group({
  characterid: [''],
  playerUID: [''],
  covenantID: [''],
  info: this.fb.group(new Info()),
  infoMagus: this.fb.group(new InfoMagus),
  characteristics: this.fb.group(new Characteristics()),
  abilities: this.fb.group(new Abilities()),
  arts: this.fb.group(new Arts()),
  armour: this.fb.group(new Armour()),
  agingWarping: this.fb.group(new AgingWarping()),
  chargen: this.fb.group(new Chargen()),
  playerChar: ['']
})

在我的home.html中，添加（示例）信息组件，如下所示：

<mat-expansion-panel>
        <mat-expansion-panel-header>
          <mat-panel-title><h3>CHARACTER INFO</h3></mat-panel-title>
        </mat-expansion-panel-header>
        <ng-template matExpansionPanelContent>
          <hr />
          <form [formGroup]="CharGenMagusForm">
            <app-info [parent]="CharGenMagusForm" (CloseThisPanel)="onClose($event)"></app-info>
          </form>             
        </ng-template>
      </mat-expansion-panel>

在info.ts中，我具有以下内容：

  @Input() parent: FormGroup;
  @Output() CloseThisPanel = new EventEmitter<any>();

  infoData: Observable<Info>;
  fgd: FormGroupDirective;
  info: FormGroup;

constructor(private characterDetailsService: CharacterDetailsService, private fb: FormBuilder, parent: FormGroupDirective) {
    this.fgd = parent;
  }

  ngOnInit() {
    this.info = this.fgd.form;
    this.info.addControl('info', this.fb.group(new Info()));
    this.infoData = this.characterDetailsService.GetCharacterInfo().pipe(
      tap(infoData => this.parent.patchValue({info: infoData}))        <-------I suspect the problem lies here???
    );
  }

在info.html中，我有：

<div [formGroup] = "parent">
  <form *ngIf="infoData | async"  formGroupName="info">

<---and all the form control stuff--->

CharacterDetailsS​​ervice使用特定的info.ts函数从Firestore获取所有数据，如下所示：

GetCharacterInfo() {
  return of<Info>(this.characterInfoData);
}

该信息模型类：

export class Info {
  public charName: string;
  public type: string;
  public covenant: string;
  public gender: string;
  public size: number;
  public bornYear: number;
  public currentYear: number;
  public charAge: number;
  public height: string;
  public weight: string;
  public hair: string;
  public eyes: string;
  public charPic: string;
  public charPicDataUrl: string;
}

我会为我要去哪里出错提供帮助。
