AwsS3S3Client::AwsS3{closure}(): Argument #1 ($e) must be of type AwsExceptionAwsException

[RaviJayagopal]

Describe the bug

The following code is resulting in the error:
AwsS3S3Client::AwsS3{closure}(): Argument #1 ($e) must be of type AwsExceptionAwsException, TypeError given, called in /home/customer/www///vendor/guzzlehttp/promises/src/Promise.php on line 203

$s3Client = new Aws\S3\S3MultiRegionClient([
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => [
'key' => $accessKey,
'secret' => $secretKey,
],
]);

$region = $s3Client->determineBucketRegion($bucketname);

The script crashes at the last line above at the determineBucketRegion call, and $region is null after the statement.

This works fine in PHP 7.x (tested up to v7.4.33), but crashes in all versions of PHP 8.x (tested up to v8.2.12).

AWS SDK:
"aws/aws-sdk-php": "3.x",
"guzzlehttp/guzzle": "7.8.",
"guzzlehttp/promises": "2.0.",

TIA for your help.

Expected Behavior

$region should have a valid region value, and the code should not crash.

Current Behavior

Code crashes at:

$region = $s3Client->determineBucketRegion($bucketname);

Reproduction Steps

$s3Client = new Aws\S3\S3MultiRegionClient([
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => [
'key' => $accessKey,
'secret' => $secretKey,
],
]);

$region = $s3Client->determineBucketRegion($bucketname);

Possible Solution

No response

Additional Information/Context

No response

SDK version used

3.x

Environment details (Version of PHP (php -v)? OS name and version, etc.)

PHP 8.x

The above issue still remains, but I found a workaround. So noting it here FWIW.

So instead of $s3Client->determineBucketRegion($bucketname), I used the following code to get the region, and I was able to get the region:

$result = $s3Client->getBucketLocation([
'Bucket' => $bucketname,
]);

$region = $result['LocationConstraint'];

Hi @RaviJayagopal, can you please confirm the SDK version that you are using? since you probably would need to update. You can verify this by running: composer show aws/aws-sdk-php | grep "versions :". I just did a test using the version 3.291.0 and I did not have any issues.

My code:

<?php
require '../vendor/autoload.php';

use Aws\S3\S3Client;

$client = new S3Client(['region' => getenv('TEST_REGION')]);
$response = $client->determineBucketRegion(getenv('TEST_BUCKET'));

print_r([$response]);

Response I got:

Array
(
    [0] => us-east-2
)

My PHP version:

USER@3c0630413e17 issue-2845 % php -v
PHP 8.3.0 (cli) (built: Nov 24 2023 13:21:02) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.3.0, Copyright (c) Zend Technologies
    with Zend OPcache v8.3.0, Copyright (c), by Zend Technologies

Please let me know.

Thanks!
