Cannot read property 'type' of undefined while using react-select with formik
the first parameter of React-Select's onChange is an option value while the first parameter of formik's handleChange is an event
React-Select: onChange(value, action) => voidFormik: handleChange(e: React.ChangeEvent<any>) => voidThat is the reason why you received this kind of error.
Here is my approach. I hope this helps you.
import React from 'react';import { Formik, Form, Field } from 'formik';import Select from 'react-select';function SelectField(FieldProps) { return ( <Select options={FieldProps.options} {...FieldProps.field} onChange={option => FieldProps.form.setFieldValue(FieldProps.field.name, option)} /> )}export default function FormikReactSelect(props) { const options = [ { value: '1', label: 'White' }, { value: '2', label: 'Yellow' }, ]; return ( <Formik> {formProps => ( <Form> <Field name='SelectColor' options={options} component={SelectField}/> </Form> )} </Formik> );}
