How to use Yup validation to make the field mandatory if 1 of the other 3 fields are not empty? I tried the following schema but got cyclic dependency issue. Thank you!

```js
const schema = yup.object().shape({
  a: yup.string().when(['b', 'c', 'd'], {
    is: (b, c, d) => !b && !c && !d,
    then: yup.string().required()
  }),
  b: yup.string().when(['a', 'c', 'd'], {
    is: (a, c, d) => !a && !c && !d,
    then: yup.string().required()
  }),
  c: yup.string().when(['a', 'b', 'd'], {
    is: (a, b, d) => !a && !b && !d,
    then: yup.string().required()
  }),
  d: yup.string().when(['a', 'b', 'c'], {
    is: (a, b, c) => !a && !b && !c,
    then: yup.string().required()
  })
}, [['a', 'b', 'c'], ['b', 'c', 'd'], ['a','c', 'd'], ['a','b','d']]) 
```
