Error: Cannot assign type 'null' to click event type Array. I have not been able to locate a solution to my issue in other related queries

Can someone assist me with my latest Angular project? I encountered an issue with the (click)="onOpenModal(null, 'add')" function call. Since it's meant to open a modal without an existing employee, I passed in null as a placeholder. However, I'm receiving an error stating that 'null' is not compatible with type 'Employee'. See below for the relevant code snippets:

app.component.html

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" style="color:white;">Employee System</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor02" aria-controls="navbarColor02" aria-expanded="false" aria-label="Toggle navigation">
  <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarColor02">
     <ul class="navbar-nav mr-auto">
        <li class="nav-item active">
           <a class="nav-link" (click)="onOpenModal(null, 'add')">Add Employee <span class="sr-only">(current)</span></a>
        </li>
     </ul>
     <form class="form-inline my-2 my-lg-0">
        <input type="search" (ngModelChange)="searchEmployees(key.value)" #key="ngModel" ngModel
         name="key" id="searchName" class="form-control mr-sm-2" placeholder="Search employees..." required>
     </form>
  </div>
</nav>

<!-- Rest of the HTML content -->

app.component.ts

export class AppComponent implements OnInit {
  // Class properties and methods

  public onOpenModal(employee: Employee, mode: string): void {
    // Function implementation for opening modals based on mode
  }
}

I am a newcomer to Angular and seeking guidance due to the differences in the latest version. Any assistance provided would be greatly valued. Thank you in advance!

Answer №1

since the function onOpenModal requires the parameters 'employee' and 'mode' to be passed in as valid values, passing null will not work.

public onOpenModal(employee: Employee, mode: string): void

Please ensure that you pass in valid parameters when calling this function.
