is there a recommended process for schedule changes (or maybe this is a user error but a cryptic error message)? i changed the schdedule intervals for my pipelines and im getting this GraphQL error:

Operation name: SchedulesRootQuery

Message: Invariant failed.

Path: ["repositoryOrError","schedules",0,"futureTicks"]

Locations: [{"line":130,"column":3}]

Stack Trace:

I think there might be an extra

in there?

yep, you're right.

We should wrap this so you get a better error message (maybe at definition time)?
