Hey, I have a SwiftData model with enum. How can I filter the data in @Query by that enum?

I'm getting an error Key path cannot refer to enum case 'weekly'.

Model:

import Foundation
import SwiftData

enum BudgetPeriod: String, Codable {
    case weekly
    case monthly
    case yearly
}

@Model
final class Budget {
    var title: String
    var amount: Double
    var period: BudgetPeriod

    init(title: String, amount: Double, period: BudgetPeriod) {
        self.title = title
        self.amount = amount
        self.period = period
    }
}

View:

struct BudgetView: View {
    @Environment(\.modelContext) var modelContext

    @Query var budgets: [Budget]
    @Query(filter: #Predicate<Budget> { $0.period == BudgetPeriod.weekly }) var weeklyBudgets: [Budget]

    var body: some View {
        NavigationStack {
            List {
                ForEach(budgets) { budget in
                        HStack {
                            Text(budget.title)
                            Spacer()
                            Text("\(budget.amount, format: .currency(code: Locale.current.currency?.identifier ?? "USD"))")
                        }
                    }

                }
            }
            .navigationTitle("Budget")
        }
    }
}

#Preview {
    BudgetView()
}
