How To Solve This Error : Attributeerror: 'nonetype' Object Has No Attribute 'reply_text'?

I've a button , it's supposed to return the ask_wikipedia function , so I used CallbackQueryHandler but when i want to call ask_wikipedia function i recive an attribute error ! Why

Solution 1:

When replying to a text message (from a MessageHandler) is fine to use update.message.reply_text, but in your case the incoming message is a managed by the CallbackHandler which receives a different object.
You can reply using

update.callback_query.message.edit_text(message)
