how to disable field based async validation if value === defaultValue

hi, i try to disable async validation (ask the server if the value exists) if the current value is the defaultValue of this field. i want to use:

//...
onChangeAsync: ({value, fieldApi}) => {
  if(value === fieldApi.form.options.defaultValues[fieldApi.name]) {
    return undefined; 
    // (or null or true, i actuallay dont know what the yup adapter needs)
  }
  return anyYupSchema;
}
//...

//...
onChangeAsync: ({value, fieldApi}) => {
  if(value === fieldApi.form.options.defaultValues[fieldApi.name]) {
    return undefined; 
    // (or null or true, i actuallay dont know what the yup adapter needs)
  }
  return anyYupSchema;
}
//...

but i got everytime "Invalid Form Values" and validation does not work. i think the return for the validation adapter should be different.

i tried also with updating the field options at form level with

fieldApi.update(updatedOptions)

fieldApi.update(updatedOptions)

but i think there is maybe a bug‽ after updating the field options, the meta field

errors

errors

undefined or null (cant remember)

undefined or null (cant remember)

instead of an empty array like after initialisation.
