SOLVED: No ObservableObject found

Getting this error in my main :

Thread 1: Fatal error: No ObservableObject of type Entries found. A View.environmentObject(_:) for Entries may be missing as an ancestor of this view.

import SwiftUI

@main
struct SimpleBreadApp: App {
    @EnvironmentObject var items : Entries

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(items) // here is the error
        }
    }
}

Also where have you defined your StateObject to create an instance of the envronment object? It should be here in the App , after the open brace.

Also the @EnvironmentObject should be moved to the view that uses the environment object.

class Entries: ObservableObject {
// code here, etc.
}
@main
struct SimpleBreadApp: App {
    @StateObject var items : Entries

// init() {   }   might be needed here if the StateObject is not initialised
//
//  init() {
//      let items = Entries()
//      _items = StateObject(wrappedValue: items)
//  }

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(items)
        }
    }
}
// in some view code file
struct MyView: View {
    @EnvironmentObject var items: Entries
