Filemaker - Authorization header 'Basic' invalid

I installed the following vendor: https://github.com/BlueFeatherGroup/eloquent-filemaker

and I'm trying to sync data from FileMaker to mysql via the API.

And my function when called the first time throws out this error, while the second time it passes properly.

This is my mistake:

   BlueFeather\EloquentFileMaker\Exceptions\FileMakerDataApiException

  Authorization header 'Basic' invalid.

This is the connection in the .env file:

FM_DB_HOST = filemaker01.server
FM_DB_USERNAME = apirest
FM_DB_PASSWORD = vkjfkdjskfs

this is the database connection in database.php

'DATABASENAME' => [
    'driver' => 'filemaker',
    'host' => env ('FM_DB_HOST', ''),
    'database' => 'DATABASENAME',
    'username' => env ('FM_DB_USERNAME', ''),
    'password' => env ('FM_DB_PASSWORD', ''),
    'prefix' => env ('FM_DB_PREFIX', ''),
    'version' => env ('FM_DB_VERSION', 'vLatest'),
    'protocol' => env ('FM_DB_PROTOCOL', 'https'),
    ],

DATABASENAME class

<? php

namespace App \ Models \ FileMaker \ DATABASENAME;

use App \ Traits \ FormatsAttributeNames;
use BlueFeather \ EloquentFileMaker \ Database \ Eloquent \ FMModel;
use Illuminate \ Database \ Eloquent \ Factories \ HasFactory;

class DATABASENAME extends FMModel
{
    use HasFactory;
    use FormatsAttributeNames;

    protected $ connection = 'DATABASENAME';
    protected $ layout = 'ApiLayout';

    protected $ fieldMapping = [
        'Article (1)' => 'Article',
        'Article2' => 'Article2',
        'BestellNr2' => 'Bestellnr_2',
    ];
}
and I have now created a command that synchronizes data from FileMaker to Mysql DB

protected $ signature = 'sync-filemaker-db {db}';

 public function handle ()
   {
       switch ($ this-> argument ('db')) {
           case 'DATABASENAME':
               $ this-> handleDATABASE ();
               break;
           default:
               $ this-> error ('No valid database provided');
               return 1;
       }

       return 0;
   }

   public static function> handleDATABASE ()
   {
       $ offset = 0;

       $ count = DATABASENAME :: count ();
       while ($ offset <$ count) {
           DATABASENAME :: offset ($ offset) -> get () -> each (function (DATABASENAME $ item) use (& $ offset) {
               $ recordId = (int) $ item-> getRecordId ();

               MYSQLTABLENAME :: updateOrCreate ([
                   'record_id' => $ recordId,
               ], DATABASENAME :: formatAttributeNames ($ item-> getAttributes ()));

               $ offset ++;
           });
       }
     dump ($ offset);
   }

and then I call my command:

php artisan sync-filemaker-db DATABASENAME

and then every time I first call the command php artisan sync-filemaker-db DATABASENAME this error pops up:

BlueFeather\EloquentFileMaker\Exceptions\FileMakerDataApiException

Authorization header 'Basic' invalid.

Does the library take the Token and then use it, but the old one stays with her, I don't know what else could be the problem?

Thanks a lot.
