NewChatMembers method dont work for big groups

[vbatalov]

Problem:

We have Update and Message Instance.

If chat group very small, we can get all new members by method getNewChatMembers(): User[]

But for example, my chat have 6000 members and method getNewChatMembers return always null.

How to smart fix:

Attention: You need set updates for Webhook.

For example:

$allowedUpdates = [
            'message',
            'callback_query',
            'chat_member',
            'my_chat_member',
        ];

$this->bot->setWebhook($page_url, allowedUpdates: $allowedUpdates)

Without allowed updates like a chat_member, Update will not send you required keys.

Smart fix for example

1. Get all request (ex. Laravel: $request->all();
2. Request has key [chat_member]['new_chat_member']
3. Do anything

Need to update package
Please add method for get ChatMember (not NewChatMembers());

Request

{
    "update_id": 450268762,
    "chat_member": {
        "chat": {
            "id": -100.....,
            "title": "********",
            "username": "*******",
            "type": "supergroup"
        },
        "from": {
            "id": 7150985510,
            "is_bot": false,
            "first_name": "Лилия",
            "is_premium": true
        },
        "date": 1745486964,
        "old_chat_member": {
            "user": {
                "id": 7150985510,
                "is_bot": false,
                "first_name": "Лилия",
                "is_premium": true
            },
            "status": "left"
        },
        "new_chat_member": {
            "user": {
                "id": 7150985510,
                "is_bot": false,
                "first_name": "Лилия",
                "is_premium": true
            },
            "status": "member"
        },
        "via_chat_folder_invite_link": true
    }
}

Note that this request does not contain the message key, so getting an Message Instance impossible

$client->on(function (Update $update) use ($bot) {
            $message = $update->getMessage();
}

//$message = null;
