Problem on migration use

Hello Codeigniter Users,

I've problem when I try to migrate some files in sequential mode.
After respect recommendations on Migrations in CI4 Userguide, I run spark command migrate, and I've got this error msg :

Code:

Type:        mysqli_sql_exception
Message:     Unknown column 'group' in 'where clause'
Filename:    /Applications/MAMP/htdocs/bl6/vendor/codeigniter4/framework/system/Database/MySQLi/Connection.php
Line Number: 329

I have this exception even specify the group into my migration files...

PHP Code:

<?php namespace App\Database\Migrations;

use CodeIgniter\Database\Migration;

class Migration_User extends Migration
{
    protected $DBGroup = 'default';

    public function up()
    {
......... 


And I still have access to the database on my web application, but same mysql connection problem on group in "where clause".

If anyone could help me.

Thanks in advance
