我懷疑我的onSubmit函數有問題。上述錯誤是我在運行應用程序時遇到的。我試圖更改我的onSubmit函數以將“title”作為有效負載，但這也不起作用協助將不勝感激。addAuctionForm:import React, {Component} from 'react'import { TextInput, Button } from 'react-native-paper'import { View } from 'react-native'import { connect} from 'react-redux'import { Formik } from 'formik'import { addAuction} from '../../actions/index'function mapDispatchToProps(dispatch) {    return {        addAuction: auction => dispatch(addAuction(auction))    }}class ConnectedForm extends Component {    constructor(props) {        super(props)        this.state = {            title: ''        }            }        render() {        return (            <Formik                onSubmit={() => addAuction(auction)}            >                {({ handleChange, handleSubmit, values}) => (                    <View>                        <TextInput                        onChangeText={handleChange('title')}                        value={auction.title}                        />                        <Button onPress={handleSubmit} title="SUBMIT"/>                    </View>                     )}            </Formik>        );    }}const Form = connect(null, mapDispatchToProps)(ConnectedForm)export default Form行動：import { ADD_AUCTION } from '../constants/action-types'export function addAuction(payload) {    return { type: 'ADD_AUCTION', payload}}減速器：import {ADD_AUCTION} from '../constants/action-types';const initialState = {    auctions: []}function rootReducer(state = initialState, action) {    if (action.type === ADD_AUCTION) {        return Object.assign({}, state, {            auctions: state.auctions.concat(action.payload)        })    }    return state}export default rootReducer;
