Python电报机器人作业队列

Question

我正在尝试设置一个每小时发送消息的机器人，我尝试了在google和stack overflow中找到的所有东西，但似乎无法使作业队列正常工作。这是我的代码，我基本上是从官方的python电报bot git hub获取的。这是代码，非常感谢您的帮助

from telegram.ext import Updater

u = Updater('bot_token', use_context=True)
j = u.job_queue

def callback_minute(context):
    context.bot.send_message(chat_id='my_chat_id', text='One message every minute')

job_minute = j.run_repeating(callback_minute, interval=10)
u.start_polling()
u.idle()

这是我得到的回溯

Error submitting job "callback_minute (trigger: interval[0:00:10], next run at: 2021-09-06 08:50:47 UTC)" to executor "default"

当您按开始键时，这将完成以下操作：

from telegram.ext import Updater, CommandHandler

updater = Updater('YOUR_BOT_TOKEN')

def callback_minute(context):
    context.bot.send_message(chat_id='my_chat_id', text='One message every minute')

def set_timer(update,context):
    due= 10  
    chat_id = update.message.chat_id
    context.job_queue.run_repeating(self.callback_minute, due, context=chat_id, name=str(chat_id))

dispatcher = updater.dispatcher
dispatcher.add_handler(CommandHandler("start", self.set_timer))
updater.start_polling()
updater.idle()
