SwiftUI -> Thread 1: Fatal error: No observable ob

I'm building an app with SwiftUI. When I was trying to display a sheet (previously Modal), this error message appears:

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

This error occurs when I'm using a @State variable to display a modal that includes a Map View using MapKit.

I'm new to Swift Programming and SwiftUI. The error message may be clear for you, but not really for my.

I don't see why and how I should implement a new Environment Object.

Is it because the station I select when taping on the CardView should be stored globally and pass the info to the dedicated view?

The view taking handling the @State

struct CardView: View {

    @EnvironmentObject var bixiModel: BixiStationCombinedListViewModel
    @State private var isModalOpen: Bool = false

    var station: BixiStationCombinedViewModel

    var body: some View {

        ZStack(alignment: .leading) {

                Card()

                StationTextInfo(station: station)

        } .onTapGesture {
            self.isModalOpen = true
            print(self.isModalOpen)
        }
        .sheet(isPresented: self.$isModalOpen) {
            BixiStationDetailView(station: self.station)
        }

    }
}

The view I'm trying to show within the sheet

struct BixiStationDetailView: View {

    @EnvironmentObject var bixiModel: BixiStationCombinedListViewModel

    var station: BixiStationCombinedViewModel

    var body: some View {
        VStack {
            MapView(coordinate: station.coordinate, name: station.name)        
        }
    }
}

Finally the Object

class BixiStationCombinedListViewModel: ObservableObject {

    init() {
        fetchDataFromApi()
    }

    @Published var stationsCombinedList = [BixiStationCombinedViewModel]()

    var stationsInformationList = [BixiStationInformationViewModel]()
    var stationsDataList = [BixiStationDataViewModel]()

    func fetchDataFromApi() {

        }        
    }
}

I can I get ride of the error message and display the proper view?

Thanks all!

You have to pass your environment object to BixiStationDetailView, otherwise it won't have anything to bind to its @EnvironmentObject.

.sheet(isPresented: self.$isModalOpen) {
    BixiStationDetailView(station: self.station)
        .environmentObject(self.bixiModel)
}

Since you're presenting BixiStationDetailView as a sheet, it isn't a subview of your CardView and therefore doesn't inherit its @EnvironmentObject.
