set first error message from an array of errors

[aryaniyaps]

I have a server which gives out errors in the following way:

{
  'field_name':  [
    'error message 1',
    'error message 2'
  ]
}

I want to just set the first error provided by my api.
What is the best way to do this?
right now, I am doing the following.

import { getIn } from 'formik';

const handleErrors = (errors, actions) => {
    Object.keys(errors).forEach((field) => {
      // set the first error we have at hand.
      actions.setFieldError(field, getIn(errors, [field, 0]));
    });
  }

Is there any better way to do this?
