title: Unexpected value 'Validators' imported by the module 'AppModule'. Please add a @NgModule annotation
body: <p>I am using angular reactive forms in my application.</p>
  
  <p>Below is my app.module.ts</p>
  
  <pre><code>import { HttpModule } from '@angular/http';
  import { environment } from './../environments/environment';
  import { BrowserModule } from '@angular/platform-browser';
  // import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
  import { NgModule } from '@angular/core';
  import { FormsModule, ReactiveFormsModule } from '@angular/forms';
  
  @NgModule({
      declarations: [
          AppComponent,
          HeaderComponent,
          FooterComponent,
          LoginComponent,
          SignupComponent,
          PagenotfoundComponent,
          HomeComponent,
          TabComponent,            
          FocusDirective,
          SearchPipe,
      ],
      imports: [
          BrowserModule,
          routing,
          HttpModule,
          FormsModule,
          ReactiveFormsModule
      ],
      providers: [{
          provide: AuthServiceConfig, useFactory: provideConfig
      },
      bootstrap: [AppComponent]
  })
  </code></pre>
  
  <p>I have no clue where it is breaking, it is working like charm in local. But when I deploy in the production I am facing this issue.</p>
