How do I verify that two different objects attribute are different?

Question

I'm new to using the Yup validation schema method and I was wondering how I could compare two object to check that one of their respective attributes are different.

For example, I have the following code:

export default Yup.object().shape({
    personA: Yup.object().shape({
        id: Yup.number()
            .typeError("Must be a valid number")
            .required("Required field")
    }),
    personB: Yup.object().shape({
        id: Yup.number()
            .typeError("Must be a valid number")
            .required("Required field")
    })
});

In this case, how can I check that the objects personA and personB do not have the same id ?

Thank you for reading :D

yup.object().shape({
  object1: yup
    .object({
      attribute1: yup.string().required(),
      attribute2: yup.string().required(),
    })
    .required(),
  object2: yup
    .object({
      attribute1: yup.string().required(),
      attribute2: yup.string().required(),
    })
    .test('different', 'Attribute values must be different', function (value) {
      const object1 = this.parent.object1 || {};
      return value.attribute1 !== object1.attribute1 || value.attribute2 !== object1.attribute2;
    })
    .required(),
});
