我正在尝试使用Python上的telegram和telegram.ext库制作一个电报机器人。我尝试将按钮的callback_data传递为嵌入式键盘的参数，但是当将键盘添加为reply_markup时，它将发送以下错误：
Traceback (most recent call last):

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
)
此外，键盘代码是：
class kb:
def kb(op = None, args = None):
if op == 'data':
keyboard = [[InlineKeyboardButton("Join", callback_data = args)]]
我真的不知道我在哪里弄错了。当我将静态文本分配给args
callback_data时，它会很好地工作
您认为这可能是什么？
答案 0 :(得分：3)
您传递的数据大小可能超过了允许的最大字节数64。 这是docs。 您可以按以下方式获取以字节为单位的数据大小。
len('YOUR DATA'.encode('utf-8'))
