Based on the information in the knowledge sources, the error message "Invalid backend configuration. Readable volumes not available." when using S3 with elFinder in Backpack is typically related to misconfiguration in either your Laravel filesystem or elFinder config files.

Here are some key points and troubleshooting steps from the sources:

1. Check Filesystem Disk Configuration
   Ensure your config/filesystems.php has the correct S3 disk configuration, including key, secret, region, bucket, and optionally url and endpoint. Example:

   's3' => [
       'driver' => 's3',
       'key' => env('AWS_ACCESS_KEY_ID'),
       'secret' => env('AWS_SECRET_ACCESS_KEY'),
       'region' => env('AWS_DEFAULT_REGION'),
       'bucket' => env('AWS_BUCKET'),
       'url' => env('AWS_URL'),
       'endpoint' => env('AWS_ENDPOINT'),
   ],

   Make sure your .env file contains the correct values for these keys.
   See example config

2. elFinder Disk Configuration
   In your config/elfinder.php, you need to specify the disk in the disks array. For S3, you should also provide the URL and alias:

   'disks' => [
       's3' => [
           'URL' => env('AWS_URL'),
           'alias' => 'S3 storage',
       ],
   ],

   This is necessary because elFinder does not automatically use the url from the Laravel filesystem config for S3.

3. CORS Settings
   You mentioned setting "AllowedOrigins": ["*"] in your S3 CORS configuration, which is correct for development, but ensure all other CORS settings (methods, headers, etc.) are also permissive enough for your use case.

4. Roots Configuration
   If you set 'roots' => [] or null, elFinder will use the disks and dir settings. Make sure you do not have conflicting or missing settings here.

5. Debugging
   Set 'debug' => true in your elFinder options to get more detailed error messages.

6. Common Pitfalls

   • Make sure the S3 bucket exists and your credentials have the correct permissions.
   • If it works locally but not on the server, double-check that your server's .env file is correct and that the server has network access to S3.
   • If you have published the elFinder config before, make sure it is up to date with the latest Backpack version, as older configs may lack necessary options.

Summary:
The most common issue is that elFinder requires the URL and alias to be set in the disks array for S3, not just in Laravel's filesystem config. Update your config/elfinder.php as shown above, and ensure your .env and S3 permissions are correct. If the problem persists, enable debug mode and check for more specific errors.

If you have already done all of the above and the issue remains, the knowledge sources do not provide further troubleshooting steps specific to your scenario. In that case, you may need to check for server-specific issues or consult the Backpack or elFinder documentation for advanced S3 integration details.
