[IONIC 4] How to solve: Cannot find 'PageModule' in 'page.module'

Hi guys !

I have a weird error with my Ionic 4 Tabs app…

ERROR Error: Uncaught (in promise): Error: Cannot find 'MesExercicesPageModule' in '../mes-exercices/mes-exercices.module'
Error: Cannot find 'MesExercicesPageModule' in '../mes-exercices/mes-exercices.module'

Here is the route in my tabs.router.module:

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { TabsPage } from './tabs.page';

const routes: Routes = [
  {
    path: 'tabs',
    component: TabsPage,
    children: [
      {
        path: 'mes-rdvs',
        children: [
          {
            path: '',
            loadChildren: '../mes-rdvs/mes-rdvs.module#MesRdvsPageModule'
          }
        ]
      },
      {
        path: 'mes-exercices',
        children: [
          {
            path: '',
            loadChildren: '../mes-exercices/mes-exercices.module#MesExercicesPageModule'
          }
        ]
      },
    ]

Here is the module:

import { IonicModule } from '@ionic/angular';
import { RouterModule } from '@angular/router';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { MesExercicesPage } from './mes-exercices.page';
import {AutosizeModule} from 'ngx-autosize';

@NgModule({
  imports: [
    IonicModule,
    CommonModule,
    FormsModule,
    RouterModule.forChild([{ path: '', component: MesExercicesPage }]),
    AutosizeModule
  ],
  declarations: [MesExercicesPage]
})
export class MesExercicesPageModule {}

I have many other pages and tabs, and everything else work well. I can’t find any difference between this module and the others.

Any ideas ?

Feel free to ask for more code !
