date().required("Required")

[donadley]

When adding a string parameter to required() ex. 'required("Required")' for yup.date the parameter is not added to the validation object when validate() is ran.

expected: Required
actual: effectiveDate must be a date type, but the final value was: Invalid Date (cast from the value "").

Yup Object used

export const = DateSchema = Yup.object().shape({
  date : Yup.object().shape({
    effectiveDate: Yup.date().required("Required"),
    expirationDate: Yup.string().required('Required'),
  })
})

Also expirationDate's error message in the validation object shows "Requred" as expected.

The issue is resolved. I needed to add .nullable().

Yup.date().required("Required").nullable().

I think I just spent 6 hours of my workday walking in circles around the problem described in this issue and this issue: #851 😅
