"Error executing "PutObject"" with AWS for PHP SDK

Hello,

I’m receiving the following error whenever I try to upload files to my DigitalOcean Spaces by way of the AWS SDK on PHP.

Fatal error: Uncaught exception ‘Aws\S3\Exception\S3Exception’ with message ‘Error executing “PutObject” on “https://SPACES.sfo2.digitaloceanspaces.com/FILEPATH/FILENAME.EXT”; AWS HTTP error: Client error: PUT https://SPACES.sfo2.digitaloceanspaces.com/FILEPATH/FILENAME.EXT resulted in a 403 Forbidden response: <?xml version=“1.0” encoding=“UTF-8”?><Error><Code>SignatureDoesNotMatch</Code><RequestId>tx000000000000084eb6bea-005e97 (truncated…) SignatureDoesNotMatch (client): - <?xml version=“1.0” encoding=“UTF-8”?><Error><Code>SignatureDoesNotMatch</Code><RequestId>tx000000000000084eb6bea-005e9740a7-443fd0-sfo2a</RequestId><HostId>443fd0-sfo2a-sfo</HostId></Error>’ GuzzleHttp\Exception\ClientException: Client error: PUT https://SPACES.sfo2.digitaloceanspaces.com/FILEPATH/FILENAME.EXT resulted in a 403 Forbidden response: <?xml version=“1.0” encoding=“UTF-8”?><Error><Code>SignatureDoesNotMatch</Code><RequestId>tx000000000000084eb6bea-005e97 (t in /var/www/vhosts/SUBSCRIPTION/DOMAIN/vendor/aws/aws-sdk-php/src/WrappedHttpHandler.php on line 195

Here’s my code:

###spaces_config.php

require '../../vendor/autoload.php';
use Aws\S3\S3Client;

$spaces = new Aws\S3\S3Client([
  'version' => 'latest',
  'region'  => 'us-west',
  'endpoint' => 'https://sfo2.digitaloceanspaces.com',
  'credentials' => [
          'key'    => 'SPACES_KEY',
          'secret' => 'SPACES_SECERT_KEY',
      ],
]);

###spaces_UPLOADBLADE.php

 $spaces->putObject([
       'Bucket' => 'SPACES',
       'Key'    => 'FILEPATH ON SPACES.$fileKey,
       'Body'   => fopen($fileTemp, 'r'),
       'ContentType' => 'image/'.$fileExtension,
       'ACL'    => 'private'
 ]);

###databaseUpload.php file that when form is submitted goes to

 $fileFile = $_FILES['fileFile'];
 $fileName = $_FILES['fileFile']['name'];
 $fileTemp = $_FILES['fileFile']['tmp_name'];
 $fileSize = $_FILES['fileFile']['size'];
 $fileError = $_FILES['fileFile']['error'];
 $fileType = $_FILES['fileFile']['type'];

 $fileExplode = explode('.', $fileName);
 $fileExtension = strtolower(end($fileExplode));

 $thumbnailExtAllow = array('jpg', 'jpeg', 'png', 'pdf');

 $thumbnailKey = $postID.".".$fileExtension;

 include '../../do_spaces/spaces_config.php';
 include '../../do_spaces/spaces_UPLOADBLADE.php';

If anyone is able to help I would greatly appreciate it!

Thanks, DevLexicon
