Model not using DBGroup

I searched the forums but it does not appear anyone else is having this issue.

I am using the myth-auth module to provide authentication to my system.  To keep things logically separated, I have a separate database for the authentication module and a separate database for my data.  I have configure the myth-auth module to use the 'default' database group, and I'm trying to configure CodeIgniter 4 to use another  database for the data.  Here is what I have.

.env

Code:

database.default.hostname = localhost
database.default.database = users
database.default.username = mysql
database.default.password = password
database.default.DBDriver = MySQLi

database.publications.hostname = localhost
database.publications.database = publications
database.publications.username = mysql
database.publications.password = password
database.publications.DBDriver = MySQLi

/app/Config/Database.php

PHP Code:

public $default = [
 'DSN'      => '',
 'hostname' => 'localhost',
 'username' => 'mysql',
 'password' => 'password',
 'database' => 'users',
 'DBDriver' => 'MySQLi',
 'DBPrefix' => '',
 'pConnect' => false,
 'DBDebug'  => (ENVIRONMENT !== 'production'),
 'charset'  => 'utf8',
 'DBCollat' => 'utf8_general_ci',
 'swapPre'  => '',
 'encrypt'  => false,
 'compress' => false,
 'strictOn' => false,
 'failover' => [],
 'port'    => 3306,
 ];
 public $publications = [
 'DSN'      => '',
 'hostname' => 'localhost',
 'username' => 'mysql',
 'password' => 'password',
 'database' => 'publications',
 'DBDriver' => 'MySQLi',
 'DBPrefix' => '',
 'pConnect' => false,
 'DBDebug'  => (ENVIRONMENT !== 'production'),
 'charset'  => 'utf8',
 'DBCollat' => 'utf8_general_ci',
 'swapPre'  => '',
 'encrypt'  => false,
 'compress' => false,
 'strictOn' => false,
 'failover' => [],
 'port'    => 3306,
 ]; 


/app/Models/FiscalYearModel.php

PHP Code:

<?php namespace App\Models;

use CodeIgniter\Model;

class FiscalYearModel extends Model {
  protected $DBGroup  = 'publications';
  protected $table = "FiscalYears";
  protected $primaryKey = "FiscalYearID";
  protected $allowedFields = ["FiscalYear"];

  public function getFiscalYear($fiscalYearID) {
    return $this->find($fiscalYearID);
  }

  public function getDBGroup() {
    return $this->DBGroup;
  }
} 


Error Message

Table 'users.FiscalYears' doesn't exist
