Laravel内无法解决的依赖性解决方案

Question

调用我创建的自定义函数时出错：

namespace App\Jobs\Device;

class UpdateUserReference {
    public $installationReference;
    public $userReference;

    // assign payload data and installation id received to command
    function __construct($bodyContent) {
        $this->installationReference = $bodyContent["installationReference"];
        $this->userReference = $bodyContent["userReference"];
    }
}

  

类App \ Jobs \ Device \ UpdateUserReference中无法解析的依赖项解析[参数＃0 [$ bodyContent]]

奇怪的是我之前从未遇到过错误，而且我创建的函数与所有其他情况完全相同。我提供的bodyContent变量有什么问题？

在以下内容中调用该函数：

public function update(Request $request) {
    // Get payload from request
    $bodyContent = json_decode($request->getContent(), true);
    $action = $bodyContent["action"];
    $installationReference = $bodyContent["installationReference"];

    switch($action) {
        case 'userReference':
            $updateUserReference = new UpdateUserReference($bodyContent);
            $result = $this->commandBus->execute($updateUserReference);
            break;
    }

    if (!empty($result)) {
        $response = [
            'error' => [
                'code' => 400,
                'message' => "Update Error"
            ]
        ];

        return $this->setStatusCode(400)->respond($response);
    }

    $response = [
        'data' => [
            'installationReference' => $installationReference
        ]
    ];

    return $this->setStatusCode(201)->respond($response);
}
