Must supply a value for form control with name: ‘nom’

I am currently trying to update data stored with MongoDB via my form (Angular).
However, I have an error in my browser console:

ERROR Error: NG01002: Must supply a value for form control with name:
‘name’

HTML :

<div class="row justify-content-center mt-5">
  <div class="col-md-4">
    <h1>Modification de vos informations.</h1>
    <form [formGroup]="updateForm" (ngSubmit)="onUpdate()">
      <div class="form-group">
        <label>Nom</label>
        <input class="form-control" type="text" formControlName="nom" required>
      </div>

      <div class="form-group">
        <label>Prénom</label>
        <input class="form-control" type="text" formControlName="prenom" required>
      </div>

      <div class="form-group">
        <label>Email</label>
        <input class="form-control" type="text" formControlName="email" required>
      </div>

      <div class="form-group">
        <label>Mot de passe</label>
        <input class="form-control" type="text" formControlName="password" required>
      </div>

      <div class="form-group">
        <label>Statut</label>
        <input class="form-control" type="text" formControlName="statut" required>
      </div>

      <div class="form-group">
        <label>NombreUC</label>
        <input class="form-control" type="text" formControlName="nombreUC" required>
      </div>

      <div class="form-group">
        <button class="btn btn-primary btn-block" type="submit">Update</button>
      </div>
    </form>
  </div>
</div>

TS :

import { Component, OnInit, NgZone } from '@angular/core';
import { Router, ActivatedRoute } from '@angular/router';
import { CrudService } from './../../../service/crud.service';
import { FormGroup, FormBuilder } from "@angular/forms";


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

  getId: any;
  updateForm: FormGroup;

  constructor(
    public formBuilder: FormBuilder,
    private router: Router,
    private ngZone: NgZone,
    private activatedRoute: ActivatedRoute,
    private crudService: CrudService
  ) {
    this.getId = this.activatedRoute.snapshot.paramMap.get('id');

    this.crudService.GetUser(this.getId).subscribe(res => {
      this.updateForm.setValue({
        nom: res['nom'],
        prenom: res['prenom'],
        email: res['email'],
        password: res['password'],
        statut: res['statut'],
        nombreUC: res['nombreUC']
      });
    });

    this.updateForm = this.formBuilder.group({
      nom: [''],
      prenom: [''],
      email: [''],
      password: [''],
      statut: [''],
      nombreUC: ['']
    })
  }

  ngOnInit() { }

  onUpdate(): any {
    this.crudService.updateUser(this.getId, this.updateForm.value)
    .subscribe(() => {
        console.log('Updated!')
        this.ngZone.run(() => this.router.navigateByUrl('/admin/list-users'))
      }, (err) => {
        console.log(err);
    });
  }
}

I’m new to this so I’m sorry if I’m not clear enough.. but I haven’t found a solution yet.
