actions/cache@1 & Scheduled Actions

Started seeing these errors today on my scheduled actions. These actions essentially run a node.js test suite

It seems to fail on the node modules cache step

##[error]Event Validation Error: The event type schedule is not supported. Only push, pull_request events are supported at this time.
##[warning]No scopes with read permission were found on the request.
##[error]Node run failed with exit code 1

Furthermore the same test does indeed pass on push and pull request events

Is there a change in the wat scheduled actions are dispatched?

Yeah, it changed recently, but check https://github.com/actions/cache/issues/107 and response from staff.
