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

For html primitive input fields handleChange works like a charm, but for custom components, you've to use setFieldValue to change the value imperatively.

onChange={e => setFieldValue('joinedAt', e)}
