Code below

$this->api = new \Aws\S3\S3Client(
array(
‘credentials’ => $credentials,
‘region’ => Cdn_Core::get_region_id( $this->_config[‘bucket_location’] ),
‘version’ => ‘2006-03-01’,
‘use_arn_region’ => true,
)
);
$result = $this->api->putObject(
array(
‘Bucket’ => $this->_config[‘bucket’],
‘Key’ => $key,
‘Body’ => $key
)
);

I tried import use Aws\S3\S3Client;
but still error persists
