Preview crashed because of a Fatal Error in ModelData.

Can anyone give me assistance on how to fix this. My preview crashed because a Fatal Error in ModelData.

This is how my ModelData looks:

import SwiftUI

struct SutraokeDetail: View {

@Environment(ModelData.self) var modelData
var sutra: Sutras


var body: some View {
    @Bindable var modelData = modelData
    
    ScrollView {
        CircleImage(image: sutra.image)
            .offset(y: -130)
            .padding(.bottom, -130)
        VStack(alignment: .leading) {
            HStack{
                Text(sutra.name)
                    .font(.title)
                
                Spacer()
                Text(sutra.text)
                
            }
        }
        
    }
}

} #Preview { let modelData = ModelData() return SutraokeDetail(sutra: modelData.sutras[0]) .environment(modelData) }
