Laravel 9 accessing AWS S3 - UnableToWriteFile at location

Question

I have built a CRUD application with Laravel, but as I want it to be hosted on heroku, using the Laravel storage is not a solution, which is why I am trying to use AWS S3.

I followed a few tutorials, and it seemed pretty straight forward to do, however I get this error : League \ Flysystem \ UnableToWriteFile Unable to write file at location: nameOfMyPicture.jpg.

What I have done so far :

I have run the command composer require league/flysystem-aws-s3-v3. I have run config:clear and cache:clear. I have run multiple times composer update.

My .env file should have the right information as well. I tried not using .env file and putting all the information directly in the filesystems.php file.

Here is the code in my query.

 if ($request->hasfile('photo')) {
            $file = $request->file('photo');

            $name = time() . '.' . $file->getClientOriginalExtension();
            $filePath = 'locations/' . $name;

            Storage::disk('s3'))->put($filePath, file_get_contents($file);

            return back()->with('msg', 'Image Uploaded successfully');
        }

When using

if (Storage::disk('s3')->exists('my-file-name.jpg')) {
            dd("hello");
        }

I get the error message : Unable to check existence for: myFileName.

When I dd(Storage::disk('s3'))->put($filePath, file_get_contents($file));, the url is null, but I do get the right bucket name, the credentials from my env file, the right region etc... Here is the dd.

The filesystems.php file concerning s3

'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'),
            'use_path_style_endpoint' => env('AWS_USE_PATH_STYLE_ENDPOINT', false),
            'throw' => true,
        ],

My .env file

AWS_ACCESS_KEY_ID=rightkey
AWS_SECRET_ACCESS_KEY=rightsecret
AWS_DEFAULT_REGION=eu-west-3
AWS_BUCKET=veville-images
AWS_USE_PATH_STYLE_ENDPOINT=false

Here is the AWS User Permission policies : user_policy.

When using the terminal, using the same AWS credentials, I have access to my bucket, and can upload and download files. However I can't through Laravel. I am at a complete loss here. Any help would be greatly appreciated.

Thank you in advance.

Are you able to perform any other commands on the bucket, such as `get` operations? Check that the `IAM` user has the correct policy permissions to access the bucket. You can check your permissions against the recommended permissions in the [Flysystem documenation](https://flysystem.thephpleague.com/docs/adapter/aws-s3-v3/). — Peppermintology, Jun 27 '22 at 08:26
@peppermintology Hello, thank you for your answer. I am not familiar with it, I didn't try to get, I will try and get back to you, thank you. I edited the post with a picture of the user permissions in IAM. — Laravel-Dog, Jun 27 '22 at 08:36

To anyone who might have the same problem. I managed to upload a file to my s3 bucket.

After looking around on the github, there was a commit not merged that would give the actual error which was : 'Error executing "PutObject" on "https://bucket.s3.region.amazonaws.com/file.ext"; AWS HTTP error: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://bucket.s3.region.amazonaws.com/file.ext'

To resolve that issue : I have a very Simple Solution to this problem. You can do this without any certificate file.

Go on Laravel Root Folder -> Vender -> guzzlehttp -> guzzle -> src

open Client.php

find $defaults Array . that looks like this way.

$defaults = [
    'allow_redirects' => RedirectMiddleware::$defaultSettings,
    'http_errors'     => true,
    'decode_content'  => true,
    'verify'          => true,
    'cookies'         => false
];

Now main Job is to change value of verify key.

'verify'          => false,

So After this, it will not check SSL Certificate for CURL Request. This Solution works for me. I find this solution after much research.

Note: 'verify' => false can create a security issue in any Live or Development server. Do not try this on Server. This solution is only for Local System. Answer found here : AWS SSL security error : [curl] 60: SSL certificate prob...: unable to get local issuer certificate

Step1: Go to config/filesystems.php

Step2: Add 'scheme'=>'http' in 's3' array:

'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'),
        'root' => env('AWS_BUCKET_ROOT')
        'scheme'  => 'http'
    ],
