Recently I've developed a telegram-bot which able to retrieve Fed-Rate Bar graph from CME group website. (https://www.cmegroup.com/trading/interest-rates/countdown-to-fomc.html) The bot runs daily (via run_daily) at every 5:25 PM HKT and pushs 10 images (media group limitation) to my bot. However, I've found that the bot occurs below warning and failed to send when the bot has started few hours ahead (etc. I started the bot at 10:00am and the print_CME_targetFedRate runs at 5:25 pm ), but if I use run_once to run immediately, my code works fine and I can retrieve those images from the bot.
WARNING - Update "None" caused error "Group send failed"

Would anyone knows what is wrong or have any idea?
Below is my code:

cme_target_FredRate_url = "https://www.cmegroup.com/trading/interest-rates/countdown-to-fomc.html#"
browser.get(cme_target_FredRate_url)
time.sleep(5)
