How would you go about including the name of the field in the error message in this version?

Hi Stefan, to achieve that I would probably use the validation function approach.

@Stefan The validation function provides you that as a 4th argument. See https://redux-form.com/7.4.2/docs/api/field.md/#-code-validate-value-allvalues-props-name-gt-error-code-optional-

@Rory In this episode example it's not explicit how you avoid getting 'property length of undefined' on validation. Maybe you should also mention that.
