I had a cron job but after switching to setup config it won’t run, not even config generation step. I think there is a chicken and an egg problem. To schedule cron run CircleCI has to generate config that contains the schedule. Is it so or I messed up something? Can I work around it by adding cron job to the setup config?
I had to use setup init because top level parameters don’t accept env_var_name type
Adding cron into setup config makes CircleCI not run at all. It probably crushes before it can report anything. Given that the project page become unavailable after I pushed the update… Could be a coincidence or a very bad sign 
It’s a known problem for a few months. Setup workflow and scheduled workflow in the same configuration
We have just announced the eventual replacement for Scheduled Workflows, see Scheduled Pipelines Are Here. This new (preview) feature supports scheduling pipelines that uses setup workflows.
Thank you for your patience, and happy building!
