Top three things to fix

Publish the calendar for the current or next service period and set feed_info feed_end_date past it.
This seasonal service has no published calendar. The last one ended 6 day(s) ago. Between service periods this is normal. But if buses are running with no published calendar, trip planners show nothing.
Effort: One export when the next period's schedule is set.
Schedule a feed re-export now so the new calendar is live well before the current one ends.
This feed's service calendar runs out within the next 30 days. If a new feed isn't published before it ends, trip planners will drop your agency and riders will see no service.
Effort: Usually a re-export from your scheduling software.
