Unable to turn Zap on, error = "Error turning Zap on: Javascript Exception: `TypeError: Cannot read property 'ID' of null`."

I’m getting this same error message on all my Zaps that have ScheduleOnce as the trigger, regardless of the action app that comes afterwards.

I’ve tried to uninstall ScheduleOnce and re-install it, I’ve tried regenerating the API code and connecting with a fresh code - it has been re-connected successfully as an app. I’ve then re-linked ScheduleOnce as the trigger in all Zaps successfully and this is pulling through test data fine. I have a green tick next to all steps in all my Zaps and no error messages within the set up steps of any Zaps. BUT still I can’t turn them on and am getting this error msg when I try.

All Zaps were working fine until this morning when I started getting error emails that a couple weren’t triggering. I’ve not made any changes to the Zap steps and I don’t understand why I can’t turn them on!

I’ve submitted a ticket to Zapier but it may be 24hrs before they reply and I can’t wait that long. Please can someone help me fix this?

Thanks, Steph
