Trailing closure passed to parameter of type 'FormStyleConfiguration' that does not accept a closure

I am working on 100 days of swiftUI on hackingwithswift.com and I cannot get some code to work. I am on day 28 project 4 and I keep getting the error in the title when I try to add a picker to a section of my form. What am I doing wrong?

//  ContentView.swift
//  BetterRest
//

import CoreML
import SwiftUI

struct ContentView: View
{
    @State private var wakeUp = defaultWakeTime
    @State private var sleepAmount = 8.0
    @State private var coffeeAmount = 1
    
    @State private var alertTitle = ""
    @State private var alertMessage = ""
    @State private var showingAlert = false
    
    static var defaultWakeTime: Date
    {
        var components = DateComponents()
        components.hour = 7
        components.minute = 0
        return Calendar.current.date(from: components) ?? Date.now
    }
    
    var body: some View
    {
        NavigationView
        {
            Form
            {
                Section
                {
                    Text("When do you want to wake up")
                        .font(.headline)
                    DatePicker("Please enter a time", selection: $wakeUp, displayedComponents: .hourAndMinute)
                        .labelsHidden()
                }
                
                Section
                {
                    Text("Desired amout of sleep")
                        .font(.headline)
                    
                    Stepper("\(sleepAmount.formatted()) hours", value: $sleepAmount, in: 4...12, step: 0.25)
                }
                
                Section
                {
                    
                    Picker("Daily coffee intake", selection: $coffeeAmount)
                        .font(.headline)
                    {
                        ForEach(1..<21)
                        {
                            Text($0 == 1 ? "1 cup" : "\($0) cups")
                        }
                    }
                }
            }
            .navigationTitle("BetterRest")
            .toolbar
            {
                Button("Calculate", action: calculateBedtime)
            }
            .alert(alertTitle, isPresented: $showingAlert) {
                Button("OK") { }
            } message: {
                Text(alertMessage)
            }
        }
    }
    
    func calculateBedtime()
    {
       do
       {
           let config = MLModelConfiguration()
           let model = try SleepCalculator(configuration: config)
           
           let components = Calendar.current.dateComponents([.hour, .minute], from: wakeUp)
           
           let hour = (components.hour ?? 0) * 60 * 60
           let minute = (components.minute ?? 0) * 60
           
           let prediction = try model.prediction(wake: Int64(hour + minute), estimatedSleep: sleepAmount, coffee: Int64(coffeeAmount))
           
           let sleepTime = wakeUp - prediction.actualSleep
           alertTitle = "Your ideal bedtime is..."
           alertMessage = sleepTime.formatted(date: .omitted, time: .shortened)
           
       } catch {
           alertTitle = "Error"
           alertMessage = "Sorry, there was a problem calculating your bedtime."
       }
        showingAlert = true
    }
}

struct ContentView_Previews: PreviewProvider
{
    static var previews: some View
    {
        ContentView()
    }
}

The problem code is here:

                {
                    
                    Picker("Daily coffee intake", selection: $coffeeAmount)
                        .font(.headline)
                    {
                        ForEach(1..<21)
                        {
                            Text($0 == 1 ? "1 cup" : "\($0) cups")
                        }
                    }
                }
