yesterday, azure automation released change broke ability link schedules or webhooks runbooks mandatory parameters. working on fix right , planning have deployed week.

as work around until fix in, can remove mandatory parameters , either include them variables in runbook or optional parameters ([parameter(mandatory=$false)]).
