Push message with Quick Reply not working

[wintermute2048]

System Informations

• Python version: 3.12.7
• SDK version: 3.14.2
• OS: Windows and Ubuntu

Expected Behavior

I want to send a message and quick-reply buttons should be displayed. I use this code:

qr = QuickReply(items=[
    QuickReplyItem(action=Action(
        label="Accept",
        text="Accept",
        type="message"),),
    QuickReplyItem(action=Action(
        label="Decline",
        text="Decline",
        type="message")),
])
message = TextMessage(
    text="Please accept or decline",
    quick_reply=qr)
pmr = PushMessageRequest(to=LINE_USER_ID, messages=[message])
print("PMR", pmr)
result = await line_bot_api.push_message(pmr)

Current Behavior

I get the following error message and the message is not sent via LINE.

HTTP response body: {"message":"The request body has 2 error(s)","details":[{"message":"must be specified","property":"messages[0].quickReply.items[0].action.text"},{"message":"must be specified","property":"messages[0].quickReply.items[1].action.text"}]}

It seems that the server complains, that the action of the quick-reply-item has no element "text".
The reason for this is that import linebot.v3.messaging.Action does not have this field.

Workaround

With the following monkey-patch, everything works fine:

import linebot.v3.messaging

class PatchedAction(linebot.v3.messaging.Action):
    text: StrictStr

linebot.v3.messaging.Action = PatchedAction

Suggested Change

Add the field text to the class Action, so that it matches to the structure described here: https://developers.line.biz/en/docs/messaging-api/using-quick-reply/#set-quick-reply-buttons

Hi, thank you for using line-bot-sdk-python, @wintermute2048!
What happens when your application uses MessageAction instead of Action?
