Yup validate array fields conditionally

So I wanted to validate few fields in array based on other boolean field. Here below is a schema of my form.

{
  "bankAccounts": [{ 
    "accountType": "savings", 
    	"accountNumber": "11111111111"
  }], 
  "bankingEnabled": true
}

Now I want that array fields to validate only if bankingEnabled is true. Here below is a Yup schema that will solve this problem:

{
  bankAccounts: yup.array()
          .when('bankingEnabled', {
            is: true,
            then: yup.array().of(
              yup.object().shape({
                accountType: yup.string().required('Please select your Account Type'),
                accountNumber: yup
                  .string()
                  .required('You must enter a Account Number')
                  .matches(/^[0-9]+$/, 'Must be only digits')
                  .min(5, 'Must be atleast 5 digits')
                  .max(17, 'Must not be more than 17 digits'),
              })
            )
          })
}

Se here's I'm checking conditionally on bankindEnabled field using when method that if value of this field is true then other validations will be executed.

Hope this helps.
