How to use custom Input with Formik in React?

Question

I\'m trying to use DatePicker within Formik. But when I click DatePicker\'s date its form value is not changed. Instead, I got this error:

Uncaught T

Answer 1

I resolve this like

 setFieldValue('joinedAt', e)}
/>

You can use e.target.value on setFieldValue's second prop, depends on your custom input design. Thanks to Brandon.
