How to tell if validate has no errors and stop the form submit.

`const submit = (values, dispatch) => {
const promise = new Promise((resolve) => {
resolve();
});
console.warn(promise);
};`

I have that as my form submit how do i work out if any of these have errored

`validate: (values) => {
const errors = {};

if (values.test === 0) {
errors.test = "test erroring"
}

return errors;
};`

i just want to do it as its a form that gets a specific form based on the fields here and i need them all to be able to submit
