What can I do to solve telegram.ext.JobQueue errors in python?

I intended to use telegram.ext.JobQueue in my code to run news() function every 30 seconds. This function sends a document for me in telegram. Here is my code:

def start(update: Update, context: CallbackContext):
    update.message.reply_text(
        "Hello, Welcome to my Bot. Please write /help to see the commands available.")
    context.job_queue.run_repeating(news, interval=30, first=10, context=update.message.chat_id)

def news(update: Update, context: CallbackContext):

    s = io.StringIO()
    csv.writer(s).writerows(newlist)
    s.seek(0)
    buf = io.BytesIO()
    buf.write(s.getvalue().encode())
    buf.seek(0)
    buf.name = f'items.csv'
    context.bot.send_document(chat_id=update.message.chat_id, document=buf)

The following line makes the error:

context.job_queue.run_repeating(news, interval=30, first=10, context=update.message.chat_id)

I got this error when I click /start in the telegram bot:

No error handlers are registered, logging exception.

What can I do to solve this problem?

As detailed in the tutorial, the example and the documentation, job callbacks take exactly one argument of type CallbackContext - not two.
