S3-to-S3 example failing

[mfragaini]

We're using the PHP S3-to-S3 example. We're encountering an error in the following lines:

                // CREATE API CLIENT
		$apiClient = new ApiClient('<our-API-key>');
		
		// CREATE ENCODING
		$encoding = new Encoding('A Name for your encoding');
		$encoding->setCloudRegion(CloudRegion::AWS_US_EAST_1);
		$encoding = $apiClient->encodings()->create($encoding);

We don't have an actual error message because this is being run within a Laravel project; the error we get is a fatal throwable exception, which tells us nothing.
