I'm attempting to save a CKQuerySubscription in production, in the public database, but I'm seeing the following error:
Failed to create CloudKit subscription for Encounter: <CKError 0x3038f66a0: "Invalid Arguments" (12/2006); server message = "attempting to create a subscription in a production container"; op = 093C69242BCC1B0A; uuid = D6E49665-6B8A-4F16-BBD8-B188A4E71F70; container ID = "iCloud.com...">
This is the query’s predicate: NSPredicate(format: "users CONTAINS %@", user.recordID), and the same subscription works perfectly fine in the development CloudKit environment. I have a queryable index on the users field in both environments. Also, I have saved a TRUEPREDICATE CKQuerySubscription in production, and that works perfectly. Does anyone know what I could be missing here?
