Angular Redux-Form初始化错误：TypeError：无法读取null属性

Question

我有一个Angular 5.2.8应用程序，其中包含angular-redux / form 6.5.0，当我的表单初始化时，我收到此错误。

    core.js:1448 ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'firstName' of null
TypeError: Cannot read property 'firstName' of null
    at Function.State.traverse (state.js:26)

在我的组件中，我导入了以下内容：

import { FormGroup, FormControl, FormBuilder, Validators } from '@angular/forms';

我像这样初始化我的表单：

 this.userForm = this.fb.group({
      firstName: ['', [<any>Validators.required]],
      lastName: ['', [<any>Validators.required]],
      email: ['', [<any>Validators.required, <any>Validators.pattern(this.emailRegex)]],
      email2: ['', [<any>Validators.required, <any>Validators.pattern(this.emailRegex)]],
      password: ['', [<any>Validators.required, <any>Validators.pattern('((?=.*\\d)(?=.*[a-z])(?=.*[A-Z]).{8,50})'), Validators.minLength(6)]],
      phone: ['', [<any>Validators.pattern('^[0-9-]{1,20}'), Validators.minLength(10)]],
      company: ['', []],
      industry: ['', [Validators.required]],
      month: ['', []],
      day: ['', []],
      year: ['', []]
    }, {validator: this.matchingEmails('email', 'email2')});

我确保减速器正确组合。实际上，这种形式在不同的开发环境中按预期工作。我已经尝试将angular-redux / form的版本更改为6.6.0和6.7.0，因为它适用于此开发人员（https://github.com/angular-redux/form/issues/53）但不适合我。任何帮助都将非常感谢，谢谢！
