Allow empty value in object that is not required

[CharlyPoppins]

Hello,

I'm struggling with this validation schema, only translations.fr is defined as required.

const validationSchema = Yup.object().shape({
    originalName: Yup.string(),
    translations: Yup.object()
      .shape({
        fr: Yup.object().shape({ alt: Yup.string().required() }).required(),
        en: Yup.object().shape({ alt: Yup.string().required() }),
      })
      .required(),
  })

What happen
The form is not valid, errors are :
translations.en.alt is a required field
translations.fr.alt is a required field

Expected
I'm trying to allow submitting the form according to these :

• if at least one filed on the required object is invalid : the form should be invalid
• if all fields of the non required object are empty : the form should be valid

Any clues ?
