Suddenly in-app purchases of already productive IAPs are failing in the production with the error code: NSUnderlyingError=0x283b42e20 {Error Domain=ASDServerErrorDomain Code=3504 "找不到此项目。" UserInfo={NSLocalizedDescription=找不到此项目。}}} Environment: Production OS Version：iOS 15.6.1 I confirm that there have been no prohibited sales areas for the product I want to know What does Code 3504 represent? Where can I find documentation related to error codes?

I used Schema and MigrationPlan to initialize the Model Container. SwiftDataDemoApp.swift Then I modified the Schema and created a MigrationStage through the custom method, which was configured in the stages array of the SchemaMigrationPlan. Models.swift But when I run the app, I don't receive the willMigrate and didMigrate callbacks Xcode Version: 15.0 beta (15A5160n) MacOS: 13.3.1 (a) (22E772610a)

I can't find the method to create ModelContainer that appears in the video at 8: 52. The code in the video is as follows: let container = ModelContainer( for: Trip.self, migrationPlan: SampleTripsMigrationPlan.self ) This method doesn't seem to exist in Xcode15. I found other method to create ModelContainer using Schema and Schema MigrationPlan in Xcode15. public convenience init(for givenSchema: Schema, migrationPlan: (SchemaMigrationPlan.Type)? = nil, _ configurations: ModelConfiguration...) throws And I tried to create a Schema to use this method, like this: let container = try! ModelContainer(for: .init([Person.self]), migrationPlan: MigrationPlan.self) But an error occurred during runtime SwiftData/ModelContext.swift:177: Fatal error: Container does not have any data stores SwiftDataDemoApp.swift How to create a ModelContainer with [PersistentModel] and SchemaMigrationPlan ?
