Angular-仅在生产版本中接收错误

Question

我有一个在开发模式下按预期运行的Angular 6应用。但是，每当我在生产模式下运行它时，我都会收到至少两个无法查明的异常错误。第一个如下：

core.js:1545 ERROR TypeError: Bo(...).onMouseLeave is not a function
    at Object.handleEvent (client.component.ngf…ild-optimizer.js:82)
    at Object.handleEvent (core.js:9865)
    at Object.handleEvent (core.js:10409)
    at Gr (core.js:7325)
    at core.js:7770
    at HTMLElement.<anonymous> (platform-browser.js:1097)
    at e.invokeTask (zone.js:421)
    at Object.onInvokeTask (core.js:3645)
    at e.invokeTask (zone.js:420)
    at t.runTask (zone.js:188)

我在启用源地图的情况下构建它；但是，core.js中的1545行只是一个块注释的开头：

    function defaultErrorLogger(console) {
    var values = [];
    for (var _i = 1; _i < arguments.length; _i++) {
        values[_i - 1] = arguments[_i];
    }
    console.error.apply(console, __spread(values));
}

Line 1545 -> /**

/**

这当然没有帮助。但是，尽管该错误令人讨厌，但该应用程序的这一部分功能正常。更令人担忧的是：

core.js:1545 ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'subscribe' of undefined

再次指向core.js中的1545行。不是很有帮助。当我尝试以“管理员”身份登录我的应用程序时，发生第二个错误。如果我尝试直接通过地址栏（登录后）导航到管理路由，也会发生此错误。

login.component.ts

    @Component({
  selector: "app-login",
  templateUrl: "./login.component.html",
  styleUrls: ["./login.component.scss"]

  pass: string;
  loginFailed: boolean;
  isLoading: boolean;
  constructor(
    private authService: AuthService,
    private userService: UserService,
    private router: Router
  ) {
    this.user = "";
    this.pass = "";
    this.loginFailed = false;
    this.isLoading = false;
  }

  ngOnInit() {
    if (this.authService.isLoggedIn) {
      if (this.userService.getIsAdmin()) {
        this.router.navigate(["/admin"]);
      } else {
        this.router.navigate(["/client"]);
      }
    }
  }

  onSubmit() {
    this.isLoading = true;
    this.authService.login(this.user, this.pass).subscribe(
      res => {
        this.isLoading = false;
        if (this.userService.getIsAdmin()) {
          this.router.navigate(["/admin"]);
        } else {
          this.router.navigate(["/client"]);
        }
      },
      er => {
        this.loginFailed = true;
        this.isLoading = false;
      }
    );
  }
}

我已经发布了我认为最有可能导致此问题的代码。不幸的是，很难说，因为该错误给了我很少的建议。我可以使用应用程序的客户端部分（尽管我收到第一个错误），并且该应用程序在开发模式下运行良好，它使用该应用程序的生产版本作为管理员根本无法正常工作。任何指针将不胜感激。
