Mandrill API错误

Question

First Time i used Mandrill API to send email,

But I got this error.

A mandrill error occurred: Mandrill_ValidationError - You must specify a key value Fatal error: Uncaught exception 'Mandrill_ValidationError' with message 'You must specify a key value' in mandrill-api-php/src/Mandrill.php:153 Stack trace: #0 mandrill-api-php/src/Mandrill.php(132): Mandrill->castError(Array) #1 mandrill-api-php/src/Mandrill/Messages.php(80): Mandrill->call('messages/send', Array) #2 mandrill.php(88): Mandrill_Messages->send(Array, false) #3 {main} thrown in Mandrill.php on line 153

This is my code

<?php

require_once 'mandrill-api-php/src/Mandrill.php';

$servername = "localhost";
$username = "root";
$password = "";
$table = '';

$conn = mysql_connect($servername, $username, $password);


if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}



$selected = mysql_select_db("DB Name")
    or die("Could not select database");

$query=mysql_query(Query);


$table .= "<table width='auto'  height='auto' border='1'  bordercolor='#003399'  style='color:#FF0000;table-layout:fixed' cellpadding=0 cellspacing=0>
<tr>
<th>User ID</th>
<th>Full Name</th>
<th>Username</th>
<th>Email ID</th>

</tr>";

while($row = mysql_fetch_array($query)) 
{ 
$table .= "<tr>";
$table .= "<td>" . $row['id'] . "</td>";
$table .= "<td>" . $row['fullname'] . "</td>";
$table .= "<td>" . $row['username'] . "</td>";
$table .= "<td>" . $row['useremail'] . "</td>";
$table .= "</tr>"; 
}
$table .= "</table><br>";


try {
$mandrill = new Mandrill(API Key);
$message = array(
    'html' => $table,
    'subject' => 'Notification Email',
    'from_email' => '[e-mail]',
    'from_name' => 'Test',
    'to' => array(
        array(
            'email' => '[e-mail]',
            'name' => 'Test',
            'type' => 'to'
        )
    ),

    'url_strip_qs' => null,
   // A mandrill error occurred: Mandrill_Unknown_Subaccount - No subaccount exists with the id 'customer-123'
throw $e;
}
?>

    'view_content_link' => null,
    'tracking_domain' => null,
    'signing_domain' => null,

);
$async = false;
$result = $mandrill->messages->send($message, $async);
print_r($result);


} 
catch(Mandrill_Error $e) {

echo 'A mandrill error occurred: ' . get_class($e) . ' - ' . $e->getMessage();

throw $e;
}
?>

<pre>/*
Before coding, you have to make configurations in Mandrill.

Step 1: Enter Mandrill and register your domain.

Step 2: Configure DNS: DKIM and SPF (This is a good tutorial: https://www.youtube.com/watch?v=uEjP_smeLjU) at https://mandrillapp.com/settings/sending-domains

Step 3: Get a KEY API (https://mandrillapp.com/settings)

Step 4: Code with PHP

Step 5: Good luck! :)
