validate: async() => is not working

[fnpen]

🐛 Bug report

<Formik validate={async() => {
      return {
        name: 'Not valid'
      }
    }} onSubmit={() => {}}>

<Formik validate={async() => {}} /> is not working. I'm using it for server validation.

Current Behavior

"errors": {}

Expected behavior

"errors": {
    "name": "Not valid"
  },

Reproducible example

Suggested solution(s)

I found an example. I need to throw exception:throw errors;

<Formik
      initialValues={{ name: '' }}
      validate={async () => {
        const errors = {
          name: 'Not valid'
        };

        throw errors; // OK
      }}
      onSubmit={() => {}}
    >

This seems to be working now. I just tried to reproduce the error in codesandbox:

Errors correctly appear in props.

Is there an issue reported about this?

For future travellers: Formik pre-2.0 used throw errors, v2.0+ uses return errors.

This issue can probably be closed.
