Backup failed because: Undefined array key "source"

[martijnderidder]

I recently upgrade my website from Laravel 8 tot 9. When i run a backup with this package, i get a strange error about Undefined array key "source".

Versions i use
"spatie/laravel-backup": "^8.0",
"laravel/framework": "^9.38"

Things i have checked

• I have a filled .env with the filled APP_NAME and filles AWS keys.
• The new configuration file has been published
• I cleared the config and run a optimize clear command.

Output

/application # php artisan backup:list
+--------+-------+-----------+---------+--------------+--------------------+--------------+
| Name   | Disk  | Reachable | Healthy | # of backups | Newest backup      | Used storage |
+--------+-------+-----------+---------+--------------+--------------------+--------------+

Ok, i did some research after this;

1. The configuration file was created like this; https://github.com/spatie/laravel-backup/blob/main/config/backup.php
2. But in this file; https://github.com/spatie/laravel-backup/blob/main/src/Tasks/Backup/BackupJobFactory.php the configuration was set like this $config['backup']['source']['files'] ... but when i do a dd($config) i get this output;

/application # php artisan backup:run
Starting backup...
array:4 [ // vendor/spatie/laravel-backup/src/Tasks/Backup/BackupJobFactory.php:13
  "backup" => array:4 [
    "backup" => array:5 [
      "name" => "Uwloon"
      "source" => array:2 [
        "files" => array:3 [
          "include" => array:2 [
            0 => "/application/storage/app"
            1 => "/application/public/uploads"
          ]
          "exclude" => array:2 [
            0 => "/application/vendor"
            1 => "/application/node_modules"
          ]
          "follow_links" => false
        ]
        "databases" => array:1 [
          0 => "mysql"
        ]
      ]
      "database_dump_compressor" => null
      "destination" => array:2 [
        "filename_prefix" => "loonloon-db"
        "disks" => array:1 [
          0 => "s3"
        ]
      ]
      "temporary_directory" => "/application/storage/app/backup-temp"
    ]
    "notifications" => array:4 [
      "notifications" => array:6 [
        "Spatie\Backup\Notifications\Notifications\BackupHasFailed" => array:1 [
          0 => "mail"

and so on....

The problem i see;

• The script is using $config['backup']['source']['files'] but should use $config['backup']['backup']['source']['files'] (than it works).

In this file; vendor/spatie/laravel-backup/src/Commands/BackupCommand.php:29 i see;
$backupJob = BackupJobFactory::createFromArray(config('backup')); ..... that looks wrong because it wil just take config, but there there is 2 layers of 'backup' first in the array.

Long story short; I had a backup file of the config file; config/backup.backup.php ... apparently Laravel throws some magic over it and make it a nested array.
