Missed required argument request in parent::__construct call

Question

I'm working on a Magento module for the past month, and everything works great on my local machine. Then I decided to release the module as a beta and test it online in a newly installed store, and after installing it from CLI, I'm getting this error:

Werules\Chatbot\Block\Webhook\Messenger Missed required argument request in parent::__construct call. File: /htdocs/magento2/app/code/Werules/Chatbot/Block/Webhook/Messenger.php

Why is that happening? Here is the file app/code/Werules/Chatbot/Block/Webhook/Messenger.php

namespace Werules\Chatbot\Block\Webhook;

class Messenger extends \Werules\Chatbot\Block\Webhook\Index
{
    protected function processRequest()
    {
        // SOME CODE HERE
    }
}

and app/code/Werules/Chatbot/Block/Webhook/Index.php

namespace Werules\Chatbot\Block\Webhook;

class Index extends \Magento\Framework\View\Element\Template
{
    protected $_helper;
    protected $_chatbotAPI;
    protected $_messageModel;
    protected $_objectManager;
    protected $_define;
    protected $_request;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Framework\ObjectManagerInterface $objectManager,
        \Werules\Chatbot\Helper\Data $helperData,
        \Werules\Chatbot\Model\ChatbotAPI $chatbotAPI,
        \Magento\Framework\App\Request\Http $request,
        \Werules\Chatbot\Model\MessageFactory $message
    )
    {
        $this->_helper = $helperData;
        $this->_chatbotAPI = $chatbotAPI;
        $this->_request = $request;
        $this->_messageModel = $message;
        $this->_objectManager = $objectManager;
        $this->_define = new \Werules\Chatbot\Helper\Define;
        parent::__construct($context);
    }
}

What I am doing wrong? Thank you.

EDIT: I'm extending another block from my module, is that a bad thing? Maybe this is the problem?

Answer 1

The error is self-explained. You forgot to inject the arguments from the parent. $context and $data are mandatory.

app/code/Werules/Chatbot/Block/Webhook/Index.php

public function __construct(
    \Magento\Framework\View\Element\Template\Context $context, // parent argument
    ......
    array $data = [] // parent argument
) {
    ......
    parent::__construct($context, $data);
}

It's normal.
