TypeError：“NoneType”对象不是可调用的telebot

Question

我是皮顿的新手。我收到了电报机器人的手杖。如果我只发送文件，一切正常，但是当我开始输入数据并生成pdf文件时，在bot中发送文件之后，我的代码就会出现错误：

Answer 1

这样啊，原来是这么回事。如果有人感兴趣的问题是在bot.register_next_step_handler。如果函数是这样的，它就不能提供参数，而不是这样：

bot.register_next_step_handler(message, send_PDF(message, name, number, info, adress))

我做了这个：

send_PDF(message, name, number, info, adress)

现在一切都很好。谢谢我自己)
