I finally finished Day 4, my first trigger.dev automation deployed to production. It checks whether NOW is a good time to change EUR into IDR: it pulls 90 days of EUR -> IDR from frankfurter.dev (keyless ECB data) and rates where today's rate sits in that range, then gives me a clear call: change or wait. The scheduling is the part i actually thought about. The frankfurter serves ECB reference rates, published once per business day around 16:00 CET, and the number doesn't move until the next working day. So running it more than once a day is pointless, a second run would just re-read the same rate. The cron job runs ONCE per weekday at 23:30 WITA, right after the publish, weekends off, no new data. So i actually know whether to change money the next day, since i'm not visiting the ATM that late anyway 😉. Only issue i had: Version mismatch detected while running in CI. Aborting. Claude Code spotted the version delta in the output and switched to the locally pinned CLI to match the SDK version.
