Require at least one set of data in array to require all fields

Hi There,

Im currently attempting to validate an array of this object shape:

export const exampleDataType = yup.object().shape({
	email: yup.string().email("Email must be valid"),
	phone: yup.string(),
	name: yup.string(),
});

with the only condition being that at least one element of the array has to require all of the fields in the above object, but not all of the elements.

Example:

VALID:

[{
	email: "",
	phone: "1234",
	name: "name"
},
{
	email: "[e-mail]",
	phone: "1234",
	name: "yup"
}] 

INVALID

[{
	email: "",
	phone: "1234",
	name: "name"
},
{
	email: "[e-mail]",
	phone: "",
	name: "yup"
}]

I’ve set up a basic sandbox, but without any real attempt to recreate as all my attemps have been absolute messes and can’t get them to work.

right, scratch what i said. .isValidSync() should do

const arrayOfExample = yup.array().compact(value => {
  return yup.object({
    email: yup.string().required(),
    phone: yup.string().required(),
    name: yup.string().required(),
  }).isValidSync(value)
}).of(exampleDataType).min(1)

the iterator will not receive a promise. async / await should return just the result.

not quite, the return value of the functions is still a promise, async/await just makes async stuff look synchronous, it doesn’t actually make it sync, code receiving the value needs to expect and handle a promise
