I consistently get an error if I try to create schedules via the UI instead of hard-coding them in the flow. Any hints where I might look to find out why?

Hi Clemens. Can you let me know if you're using Prefect Server or Prefect Cloud. And what version of Prefect Core you are using to register your flow?

Prefect-Server on a Kubernetes cluster. For Core I tried out 0.14.15 and 0.15

Thanks. That screenshot actually looks like it's coming from an old (maybe 0.14.15) version of the UI. We've made a few changes to schedules in the UI since that version (including a fix to that verb). If you can, I'd try updating your UI/server image and see if that fixes it for you.

cool, will try that!
