I found a bug to report

Please use the following template to ensure maintainers can reproduce the bug and solve it quickly.

Bug reports that do not follow this template will be kept closed because not-reproducible until the creator edits the post properly.

Steps to reproduce

• In a conversation, add a user (or bot)
• Telegram will send a request like that: { "update_id": xxxxxxx, "message": { "message_id": 6448, "from": { "id": 9999999999, "is_bot": false, "first_name": "nimbus" }, "chat": { "id": -999999999999, "title": "test reaction", "type": "group", "all_members_are_administrators": true }, "date": 1723468164, "new_chat_participant": { "id": 9999999999, "is_bot": false, "first_name": "nimbus" }, "new_chat_member": { "id": 9999999999, "is_bot": false, "first_name": "nimbus" }, "new_chat_members": [ { "id": 9999999999, "is_bot": false, "first_name": "nimbus" } ] } }
• Break in Post method of the Webhook
• The update is parsed as Message but the field Update.Message.NewChatMembers is null and Update.Message.Type is Unknown.

Expected behavior

Update.Message.NewChatMembers is filled with data from the Telegram request

Actual behavior

Update.Message.NewChatMembers is null

works for me. (tested with your exact request) make sure you've configured webhook JSON settings according to https://telegrambots.github.io/book/3/updates/webhook.html

Ok, my bad if work well, but on the migration page https://telegrambots.github.io/book/migrate/Version-21.x.html, the link for webhook migration is broken https://telegrambots.github.io/book/migrate/3/updates/webhook.html instead of https://telegrambots.github.io/book/3/updates/webhook.html Please fix
