I'm having what appears to be (?) a related issue, @ScottShearer . I have a trigger set to run every 1 month, then in the trigger Settings, I've added this condition:
@and(equals(utcNow('DD'),'01'), equals(utcNow('MM'),'08'))
When I test the flow without this condition, it runs fine. When the trigger condition is there, the flow fails with the ambiguous "Cannot read properties of undefined (reading 'properties')" error.
