guzzle 6 500内部服务器错误BadMethodCallException laravel php

我正试着大口大口地提出要求。我有两个条件，当数据有令牌，然后继续if或else。else部分在发送时正常工作，但如何像这样传递头，它显示内部服务器错误

$data如下所示：

试试看

所以我需要分别传递标题

    if (isset($data['token'])){

    $headers = [
        'Authorization' => 'Bearer '.$data['token'],
        'Content-Type' => 'application/json'
    ];


    $response = $client->request($requestType,$url,
    [
       'json' => [
           'header' => $headers,
           'data' => $data
       ]
]);

}
else{
   $headers = [
       'content-type' => 'application/json'
   ];
    $response = $client->request($requestType,$url,
    [
        'json'   => $data

]);
}

$contents = json_decode($response->getBody()->getContents(), true);           
return $contents;

$response = $client->request($requestType,$url,
    [
       'json' => $data,
       'headers' => $headers,
]);
