python-3.x - Telegram Bot 错误 - telegram.error.BadRequest : Button_data_invalid

Question

我正在尝试使用 telegram 制作 Telegram Bot 和 telegram.ext Python 上的库。我尝试通过 callback_data用于将按钮作为内联键盘的参数，但在将键盘添加为 reply_markup 时，它发送以下错误:
Traceback (most recent call last):

raise BadRequest(message)
telegram.error.BadRequest: Button_data_invalid
代码如下:
p1 = "%s(@%s)"%(query.from_user.first_name,query.from_user.username)
text = "<b>⚔Duel</b>\nChallenger %s is ready!\nWaiting for an opponent..."%p1
args = '{"next":"player2","p1":"%s","text":"%s"}'%(p1,text)
reply_markup = InlineKeyboardMarkup(kb.kb(op = "data",args = args))
bot.edit_message_text(
text=text,
inline_message_id=query.inline_message_id,
parse_mode=ParseMode.HTML,
reply_markup=reply_markup
)
另外，键盘的代码是:
class kb:
def kb(op = None, args = None):
if op == 'data':
keyboard = [[InlineKeyboardButton("Join", callback_data = args)]]
我真的不知道我错在哪里了。当代替 args 时它运行良好我将静态文本分配给 callback_data
你认为它可能是什么？

您传递的数据大小可能超过了 64 的最大允许字节数。
这是docs .
您可以按如下方式获取以字节为单位的数据大小。

len('YOUR DATA'.encode('utf-8'))
