How to have react-datepicker update Formik nested object - reactjs

Question

So I set up datepicker within my form like so
<FieldArray
name="config"
render={(arrayHelpers) => (
<div>
{values.config.map((config, index) => (
<div key={index}>
...
<DatePicker
name={`config.${index}.date`}
type="date"
value={values.date}
className={
"form-control" +
(errors.date&& touched.date
? " is-invalid"
: "")
}
onChange={(e) =>
setFieldValue("date", e)
}
/>
The data is added to the state but as an additional field instead of updating the initial state within formik. It updates likes this.
{"domain_url":"","schema_name":"","name":"","config":[{"first":"","last":"","email":"","date":""}],"date":"2020-06-10T04:00:00.000Z"}
I would appreciate any ideas.
below is a new edit of the majority of the code.
the datepicker is not displaying the date within the form field but it is updating the state correctly, now I just need it to display correctly within the form and format the date to drop the string at the end
static propTypes = {
addTenant: PropTypes.func.isRequired,
};
onSubmit = (values) => {
values.preventDefault();
this.props.addTenant(values);
};
render() {
const {
domain_url,
schema_name,
name,
config,
} = this.state;
const TenantSchema = Yup.object().shape({
domain_url: Yup.string()
.max(255, "Must be shorter than 255 characters")
.required("Client URL header is required"),
schema_name: Yup.string()
.max(255, "Must be shorter than 255 characters")
.required("Client db name is required"),
name: Yup.string()
.max(255, "Must be shorter than 255 characters")
.required("Client name is required"),
});
return (
<div className={s.root}>
<Formik
initialValues={{
domain_url: "",
schema_name: "",
client_name: "",
config: [
{
date: "",
Tenant_description: "",
},
],
}}
// validationSchema={TenantSchema} this is commented off because it breaks
submittions
onSubmit={(values, { setSubmitting, resetForm }) => {
setSubmitting(true);
values.domain_url = values.domain_url + ".localhost";
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
resetForm();
setSubmitting(false);
}, 100);
}}

Change your name,value and onChange as following
import { FieldArray, getIn } from 'formik';
<DatePicker
name={`config[${index}]['date']`}
selected={getIn(values, `config[${index}]['date']`) || ''}
value={getIn(values, `config[${index}]['date']`) || ''}
onChange={(e) =>
setFieldValue(`config[${index}]['date']`, e);
}
/>
