Signature V4 requires AWS credentials for request signing

[jack20211101]

Describe the bug

I configured [AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY] in .env, and S3Client can be called normally in Windows, but it prompts in Linux: vendor/aws/aws-sdk-php/src/Auth/AuthSchemeResolver.php",85,"Could not resolve an authentication scheme: Signature V4 requires AWS credentials for request signing, I don’t understand why.
Use the following method to work properly:

use Aws\S3\S3Client;
use Aws\Credentials\Credentials;

$credentials = new Credentials('your-access-key-id', 'your-secret-access-key');

$s3Client = new S3Client([
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => $credentials,
]);

In addition, the published configuration file config/aws.php
AWS_REGION should be AWS_DEFAULT_REGION in laravel

Hi all,

Sorry to hear about the issues. Could you both provide me with a little more information on how you're providing AWS credentials to your application? I saw the example @jack20211101 provided above, but (correct me if I'm wrong) it looks like you're just providing an example of something that works for you right now.

My configuration in .env

AWS_ACCESS_KEY_ID=my_id
AWS_SECRET_ACCESS_KEY=my_key

This is config/aws.php

'credentials' => [
'key' => env('AWS_ACCESS_KEY_ID', ''),
'secret' => env('AWS_SECRET_ACCESS_KEY', ''),
],
'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
'version' => 'latest',
'ua_append' => [
'L5MOD/' . AwsServiceProvider::VERSION,
],

And in Windows config('aws')
The content obtained

array:4 [
"region" => "us-east-1"
"version" => "latest"
"ua_append" => array:1 [
0 => "L5MOD/3.7.0"
]
"credentials" => array:2 [
"key" => "my_id"
"secret" => "AWS_SECRET_ACCESS_KEY"
]
]

In the Linux environment, credentials disappears

array:4 [
"region" => "us-east-1"
"version" => "latest"
"ua_append" => array:1 [
0 => "L5MOD/3.7.0"
]
]
