How to fix "There was a problem with your request." in Cloudkit console?

I Found my iCloud data all removed in my developing app yesterday. I seems I can continuous add record to iCloud and fetch them, but I can not check the record in Cloudkit console. It failed loading zones in Private Database. (I was tried to Reset Development Environment)

Same problem here.

"Reset Development Environment" will delete ALL your Records and your Custom Zones.

Did you add an index to your RecordType using the console? "Add Basic Index" > make "recordName" QUERYABLE. The reset will delete your indexes
