Laravel 7 - Trait 'Laravel\Sanctum\HasApiTokens' not found - php

Question

I am working with iframes and I am trying to compare the user's email with the teacher's email with eloquent. That would be the condition to list only the groups of that teacher, but it gives me this error:
Trait 'Laravel\Sanctum\HasApiTokens' not found
This is my function
public function index($id)
{
$email = User::select('email')->where('id', $id)->get();
$groups= DB::table('groups')
->join('teacher_group', 'grupo_profesor.idGrupo', '=', 'groups.idGrupo')
->join('teachers', 'teachers.idTeacher', '=', 'teacher_group.idTeacher')
->join('level_group', 'level_group.idGroup', '=', 'groups.idGroup')
->join('levels', 'levels.idLevel', '=', 'level_group.idLevel')
->join('courses', 'courses.idCourse', '=', 'levels.idCourse')
->join('programs', 'programs.idProgram', '=', 'courses.idProgram')
->where('teachers.email', '=', $email)
->paginate(10);
return view('teacherGroups.index', compact('groups','email'));
}
The sidebar button
<button class="list-group-item list-group-item-action small text-secondary"
onclick="crearTabAndIframe('TeacherGroups','teacherGroups');
Loadiframe('{{ url('Groups/Teacher/'.auth()->user()->id)}}','ifrmTeacherGroups')">
<i class="material-icons">list</i> #lang('menu.List')
</button>
This is the index view
#foreach($groups as $group)
<tr>
<td class="small text-center">{{$group->idGroup}}</td>
<td class="small text-center">{{$group->levelName}} {{$group->courseName}} {{$group->programName}}</td>
<td class="small text-center">{{$group->teacher_name}}</td>
<td class="small text-center">
<div class="row small">
<div >
<!--VIEW-->
<button onclick="seeGroup({{$group->idGroup}})" class="btn btn-sm btn-outline-success">
<i class="material-icons">remove_red_eye</i>
</button>
</div>
</div>
</td>
</tr>
#endforeach
And with the error it shows me this part of my model
class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;
/**
* The attributes that are mass assignable.
*
* #var string[]
*/
protected $fillable = [
'name',
'email',
'password',
];

Answer 1

Try This, looks like you need to install sanctum
composer require laravel/sanctum

Answer 2

I guess SanctumServiceProvider is not automatically registered in your application. To resolve your issue, you should add the service provider manually in config/app.php.
'providers' => [
//...
Laravel\Sanctum\SanctumServiceProvider::class,
];
