Invalid commute time rule: building names cannot be empty in entry 'Main Building'.
Last updated: Mar 23, 2026
At a glance
A commute time rule contains an empty building name.
What causes this error
We've detected a commute time rule that includes an empty building name. This often happens if there's a trailing comma or an accidental space where a building name should be. Every entry in your commute time rules must be a valid, non-empty building name.
How to fix it
- Check your constraints — Go to Timetable constraints and locate the commute time rules.
- Clean up the entry — Make sure every building name is filled in correctly and remove any extra commas or empty values between entries.
