当我运行命令ng serve --prod我有这个问题：
ng:///home/cristopher_ramirez/Development/angularProjects/lazyPagesRouterTest/src/app/service-order/add-service-order/add-service-order.component.html (28,51) 中的错误：类型参数' FormGroup 不可分配给“ServiceOrder”类型的参数。
“FormGroup”类型中缺少属性“cylinderRefsList”。
请注意，这只发生在我使用 --prod 命令时。
这是我的 HTML 代码（add-service-order.component-html）：
<div class="container">
<form [formGroup]="serviceOrderForm" novalidate (ngSubmit)="save(serviceOrderForm)">
<div formArrayName="cylinderRefsList">
<div class="card cardCylinder">
<div *ngFor="let cylinder of serviceOrderForm.controls['cylinderRefsList']['controls']; let i=index" class="panel panel-default">
<div class="card-header">
<span>Cilindro {{i + 1}}</span>
<button type="button" class="close" aria-label="Close" *ngIf="serviceOrderForm.controls['cylinderRefsList']['controls'].length > 1"
(click)="removeCylinder(i)">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="card-body" [formGroupName]="i">
<app-cylinder [group]="serviceOrderForm.controls['cylinderRefsList']['controls'][i]"></app-cylinder>
</div>
</div>
</div>
</div>
我正在关注本指南 https://scotch.io/tutorials/how-to-build-nested-model-driven-forms-in-angular-2 所以你可以看到我实际上在表单组中添加了 cylinderRefsList（我的 TS文件与指南几乎相同）唯一的区别是我使用模型而不是界面。
编辑 1：这是我的 TS 文件

constructor(
private router: Router,

private fb: FormBuilder,
private userService: UserService
) {
this.structureService.getAllStructures().subscribe(data => {
this.structures = data;
console.log(this.structures);
});
this.role = this.userService.getRoleUser();
}
ngOnInit() {
this.serviceOrderForm = this.fb.group({
cylinderRefsList: this.fb.array([])
