Error occurs in the template of component EmployeeCreateComponent

Question

I'm new to Angular and working on httpclient and httpservice project of CRUD application. While compiling with ng serve in VS code I get the following error:

error: ERROR in src/app/employee-create/employee-create.component.html:18:65 - error TS2554: Expected 1 arguments, but got 0.

employee-create.component.html

<div class="container custom-container">
  <div class="col-md-12">
    <h3 class="mb-3 text-center">Create Employee</h3>

    <div class="form-group">
      <input type="text" [(ngModel)]="employeeDetails.name" class="form-control" placeholder="Name">
    </div>

    <div class="form-group">
      <input type="text" [(ngModel)]="employeeDetails.email" class="form-control" placeholder="Email">
    </div>

    <div class="form-group">
      <input type="text" [(ngModel)]="employeeDetails.phone" class="form-control" placeholder="Phone">
    </div>

    <div class="form-group">
      <button class="btn btn-success btn-lg btn-block" (click)="addEmployee()">Create Employee</button>
    </div>

  </div>
</div>

employee-create component.ts

import { Component, OnInit, Input } from '@angular/core';
import { Router } from '@angular/router';
import { RestApiService } from "../shared/rest-api.service";

@Component({
  selector: 'app-employee-create',
  templateUrl: './employee-create.component.html',
  styleUrls: ['./employee-create.component.css']
})
export class EmployeeCreateComponent implements OnInit {

  @Input() employeeDetails = { name: '', email: '', phone: 0 }

  constructor(
    public restApi: RestApiService, 
    public router: Router
  ) { }

  ngOnInit() { }

  addEmployee() {
    this.restApi.createEmployee(this.employeeDetails).subscribe((data: {}) => {
      this.router.navigate(['/employees-list'])
    })
  }

}

Answer 1

addEmployee() { // <=== dataEmployee Parameter     this.restApi.createEmployee(this.employeeDetails).subscribe((data: {}) => {
    this.router.navigate(['/employees-list'])
  })
}

you are not passing a Parameter in Html file but you are trying to get parameter in ts that's why you are getting Error.
