//


// These assume you have the associated AWS keys stored in
// the associated system environment variables
$clientPrivateKey ="private key";
// These two keys are only needed if the delete file feature is enabled
// or if you are, for example, confirming the file size in a successEndpoint
// handler via S3's SDK, as we are doing in this example.
$serverPublicKey = "key";//$_SERVER['PARAM1'];
$serverPrivateKey = "private key";//$_SERVER['PARAM2'];

// The following variables are used when validating the policy document
// sent by the uploader: 
$expectedBucketName = "bucket name";

Answer 1

This error is common for when your region isn't matched correctly. You may want to double check that the region you specify in your code matches the bucket you created.
