I am getting this error when passing a function as props to a component. But I can't figure out what's going on. Thanks in advance

import {useState} from 'react'

function TaskForm(createTask) { const [title, setTitle] = useState('');

const handleSubmit = (e) =>{
    e.preventDefault();
    const newTask = {
        title
    };
    createTask(newTask)
}

return (
        <form onSubmit={handleSubmit}>
            <input placeholder="Escribe tu tarea"
                onChange={(e)=> setTitle(e.target.value)}
            />
            <button>
                Guardar
            </button>
        </form>
)

}

export default TaskForm

import TaskList from './TaskList' import TaskForm from './TaskForm' import {tasks as data} from './tasks' import {useState,useEffect} from 'react'

function App (){ const [tasks, setTasks] = useState([]);

useEffect(()=>{
    setTasks(data);
},[]);
function createTask(task){
    setTasks([...tasks,task])
} 

return (
    <>
        <TaskForm createTask={createTask}/>
        <TaskList tasks={tasks}/>
    </>
)

}

export default App;

Try to get data from props via destructuring as we are getting props as object

import {useState} from 'react'

function TaskForm({ createTask }) { 
const [title, setTitle] = useState('');

const handleSubmit = (e) =>{
    e.preventDefault();
    const newTask = {
        title
    };
    createTask(newTask)
}

return (
        <form onSubmit={handleSubmit}>
            <input placeholder="Escribe tu tarea"
                onChange={(e)=> setTitle(e.target.value)}
            />
            <button>
                Guardar
            </button>
        </form>
)
}

or you can try as:

import {useState} from 'react'

function TaskForm(props) { 
const { createTask } = props;
const [title, setTitle] = useState('');

const handleSubmit = (e) =>{
    e.preventDefault();
    const newTask = {
        title
    };
    createTask(newTask)
}

return (
        <form onSubmit={handleSubmit}>
            <input placeholder="Escribe tu tarea"
                onChange={(e)=> setTitle(e.target.value)}
            />
            <button>
                Guardar
            </button>
        </form>
)
}
