Question

我有以下代码：

＆＃13;

<?php
echo('Success');

//Setup the API
require 'vendor/autoload.php';
use Aws\Lambda\LambdaClient;

//Login to the Dynamo DB
$client = LambdaClient::factory(array(
'version' => 'latest',
  'region'  => 'us-east-1',
  'credentials' => array(
    'key' => 'My Key',
    'secret'  => 'My Secret',
  )
));

$rawdata = file_get_contents('php://input');

//echo("Raw Data:");
//echo($rawdata);

$client->invoke([
	'FunctionName' => 'LocationUpdate',
	'InvocationType' => 'Event',
	'Payload' => $rawdata
]);

＆＃13;

当我运行代码时，没有调用类型，它工作得很好。但是，当我使用调用类型为Event或DryRun来运行它时，它不起作用，而是抛出以下错误。我做错了什么？

＆＃13;

我继续下载PHAR lambda文件，而不是使用之前使用的过时技术（guzzle），它现在运行得很好。
