Summary

Fatal error: Call to a member function getChat() on null in BotManager.php:505

How to reproduce

answer() InlineQuery with InlineQueryResult*[] containing input_message_content and reply_markup with InlineKeyboard with callback_data-button, then choose that item from result then click inline button to get CallbackQuery above.

Tested in PM/Saved Messages chat.

Can you share the code where you're trying to execute getChat please?

It's possible that you're trying to access the wrong object in your response.

<?php

namespace Longman\TelegramBot\Commands\SystemCommands;

use Longman\TelegramBot\Commands\SystemCommand;
use Longman\TelegramBot\Entities\InlineKeyboard;
use Longman\TelegramBot\Entities\InlineQuery\InlineQueryResultArticle;
use Longman\TelegramBot\Entities\InputMessageContent\InputTextMessageContent;
use Longman\TelegramBot\Entities\ServerResponse;

class InlinequeryCommand extends SystemCommand
{
    protected $name = 'inlinequery';
    protected $description = 'Handle inline query';
    protected $version = '1.2.0';
    public function execute(): ServerResponse
    {
        $inline_query = $this->getInlineQuery();
        return $inline_query->answer([
            new InlineQueryResultArticle([
                'id'                    => '001',
                'title'                 => 'Title',
                'description'           => 'Description',

                'input_message_content' => new InputTextMessageContent([
                    'message_text' => 'Message',
                ]),
                'reply_markup' => new InlineKeyboard([
                    ['text' => 'Button', 'callback_data' => 'data'],
                ]),
            ]),
        ]);
    }
}

Just click button "Button".

Right, then the error must be in your CallbackqueryCommand.php, not InlinequeryCommand.php.

Can you share your CallbackqueryCommand.php file and also a more detailed stack trace of the error please?

Tested with sample example from here example-bot:CallbackqueryCommand

In this case callback_query has no chat property in result as it has with message e.g.

{
  "ok": true,
  "result": [
    {
      "update_id": ...,
      "message": {
        "message_id": ...,
        "from": {
          "id": ...,
          ...
        },
        "chat": {
          "id": ...,
          ...
        },
        "date": ...,
        "text": "...",
        "entities": [
            ...
        ]
      }
    }
  ]
}

vs

{
  "ok": true,
  "result": [
    {
      "update_id": ...,
      "callback_query": {
        "id": "...",
        "from": {
          "id": ...,
          ...
        },
        "inline_message_id": "...",
        "chat_instance": "...",
        "data": "..."
      }
    }
  ]
}

Temporary fixed with help of \TelegramBot\TelegramBotManager\BotManager::setCustomGetUpdatesCallback like this:

        } elseif ($update_content instanceof CallbackQuery) {
            /** @var CallbackQuery $update_content */
            $message = $update_content->getMessage();
            $chat_id = ($message!==null && $message->getChat()!==null) ? $message->getChat()->getId() : null;

Ah! I see now what's going on, the response of an inline button is different when it comes through an inline query. Thanks for pointing that out 👍

Would you like to make a PR to fix this? 😃
