Errors in Ionic 6 involving the FormBuilder, FormGroup, Validators, FormControl, and ControlContainer

I am currently working on creating a basic registration form using Ionic 6.12.3 ionic -V, Angular CLI version 11.0.5, and npm version 6.14.11. You can find the repository for this project here: Repo.

Below is my implementation for the register.page.ts:

// Code omitted for brevity

And here is the corresponding register.page.html:

<!-- HTML code omitted for brevity -->

In addition to that, here is the snippet from app.module.ts:

// Code excluded for conciseness

Although I have included 

import { ReactiveFormsModule, FormsModule } from '@angular/forms';
in my app module, declared FormGroup Credentials in register.page.ts, and utilized it within register.page.html, I am encountering the following error:

Error: NodeInjector: NOT_FOUND [ControlContainer]
// Detailed error message displayed above

This issue has left me puzzled even after perusing through several resources. Surprisingly, the login page appears to function correctly, even without importing ReactiveFormsModule in app.module.ts.

For more information, please refer to the repository link: Repo

Thank you for your assistance :)

Answer №1

In the IONIC framework, there are instances where you need to import certain elements in YourPage.module.ts.

Make sure to import them on the specific page you are working on:

import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({    
imports: [
        ...
        ReactiveFormsModule,
        FormsModule,
