In react, formik and yup how to skip validation if dynamic array value if undefined or empty make it optional

This is my aaray :

translator_services: (4) [empty × 3, {translator_category_description: "sa",translator_category_id: "6672a5a8b07e9bc1b7e36a5c",translator_category_type_id: ['6672a5a8b07e9bc1b7e36a5a']}]

This the error from Yup :

translator_services: Array(3)<br>
0: {translator_category_id: 'Required', translator_category_description: 'Description is required.'}<br>
1: {translator_category_id: 'Required', translator_category_description: 'Description is required.'}<br>
2: {translator_category_id: 'Required', translator_category_description: 'Description is required.'}<br>

This is validation code :

translator_services: Yup.array().of(
    Yup.object().shape({
      translator_category_id:
        Yup.string().required("Required"),
      translator_category_description:
        Yup.string().nullable().required("Description is required."),
      
      translator_category_type_id: Yup.array().nullable().min(
        1,
        "Select at least one service type"
      ),
    })
  ),

Should only validate if the array value is defined or not empty else skip the validation.
Thanks in advance
