Laravel – Delete Files when using CloudFront

I’m running a website using laravel (v.10), filament (v.3) and I’m using SpatieMediaLibrary (updated to latest version) for uploading files to aws. I serve the content through CloudFront.

My bucket policy for the moment is:

{
"Version": "2012-10-17",
"Id": "PolicyForCloudFrontPrivateContent",
"Statement": [
    {
        "Sid": "AllowCloudFrontServicePrincipal",
        "Effect": "Allow",
        "Principal": {
            "Service": "cloudfront.amazonaws.com"
        },
        "Action": [
            "s3:GetObject",
            "s3:DeleteObject"
        ],
        "Resource": "arn:aws:s3:::xxxxxx.xxx/*",
        "Condition": {
            "StringEquals": {
                "AWS:SourceArn": "arn:aws:cloudfront::xxxxx:distribution/xxxxxx"
            }
        }
    }
]}

My config/filesystems.php (please notice the variable AWS_S3_CLOUDFRONT):

  'disks' => [

    'local' => [
        'driver' => 'local',
        'root' => storage_path('app'),
        'throw' => false,
    ],

    'public' => [
        'driver' => 'local',
        'root' => storage_path('app/public'),
        'url' => env('APP_URL') . '/storage',
        'visibility' => 'public',
        'throw' => false,
    ],

    's3' => [
        'driver' => 's3',
        'key' => env('AWS_ACCESS_KEY_ID'),
        'secret' => env('AWS_SECRET_ACCESS_KEY'),
        'region' => env('AWS_DEFAULT_REGION'),
        'bucket' => env('AWS_BUCKET'),
        'folder' => env('AWS_FOLDER'),
        'view_url' => env('AWS_VIEW_URL'),
        'url' => env('AWS_S3_CLOUDFRONT'),
        'endpoint' => env('AWS_ENDPOINT'),
        'use_path_style_endpoint' => env('AWS_USE_PATH_STYLE_ENDPOINT', false),
        'throw' => true,
    ],

Before using cloudfront whenever i updated or deleted the files they were deleted from the bucket. But since I moved to serving with cloudfront, I’m able to create but not delete/replace. It’s not a cache issue, I’m confirming this directly on the bucket, logged as root (login via browser https://xxx.console.aws.amazon.com/s3/buckets) .

There are no errors on laravel logs, it still deletes/updates on the database but not in filesystem.

For clarification, I’m deleting using the SpatieMediaLibraryFileUpload component.

I’ve also tested with "Principal":"*" but the file still remained .

I’m kind of new in cloudfront, what am I missing here?

desired behavior: when updating/deleting the files using the package component (SpatieMediaLibraryFileUpload) the file should also be updated/deleted in the filesystem.
specific problem or error: Not sure here due to lack of logs, but my understanding is that it’s due to the usage of cloudfront

    Found the issue.

    It was a problem with my CustomPathGenerator class for the media package, namely on the getPath function:

     public function getPath(Media $media) : string
    {
        if ($media->model_type === 'agent') {
            return 'cms/agentes/' . Agent::find($media->model_id)->slug .'/';

        }elseif ($media->model_type === 'store') {
            return 'cms/lojas/' . $media->model_id  .'/';
        }
        
        return $media->getKey();
        
    }

    CloudFront caches files in each edge location. Here’s how it works:

    • A user in Location A requests the object
    • The request is sent to the CloudFront edge location closest to Location A
    • If the file is not in the cache, then CloudFront fetches it from the origin (in your case, an Amazon S3 bucket), stores it in the edge location’s cache and then serves it to the user
    • If another user in Location A then requests the file, it is served from the cache (as long as it is within the expiration period)

    If you want to stop a file from being served from the cache, you need to invalidate them from the CloudFront cache. This will remove them from all edge location caches, causing CloudFront to re-fetch them from the origin, or give an error if the file no longe exists.
