LAMBDA異步調用拋出錯誤，同步調用工作正常

-1

<?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([ 
 
\t 'FunctionName' => 'LocationUpdate', 
 
\t 'InvocationType' => 'Event', 
 
\t 'Payload' => $rawdata 
 
]);

當我運行的代碼，而無需調用類型，它的偉大工程。但是，當我使用Event或DryRun調用類型運行它時，它不起作用，而是引發以下錯誤。我究竟做錯了什麼？

裏面是什麼'$ rawdata'？你爲什麼要聲明'$ contxt'而不是使用？ –

上下文來自我很久以前獲得的一些示例代碼。（哎呀！），原始數據是php的輸入。我正在使用以下的「{」Serial「：」GP40ovf9「，」Lat「：」34.0「，」Lon「：」 - 84「，」SoC「：」100「，」準確性「：」8.0「 – Reid
