to.have.type() not recognized

[dschinkel]

I've got a testHelpers file that contains the following amongst other things that I've stripped out for this issue just to simplify what I'm showing:

test.helpers

import chai, { expect } from 'chai';
import chaiEnzyme from 'chai-enzyme';
chai.use(chaiEnzyme());

export {
  expect,
 };

I'm trying to use to.have.type() but get the error TypeError: (0 , _test.expect)(...).to.have.type is not a function:

some.spec.js

import { expect } from 'test/test.helpers';

//further down:

it.only('renders a 500 error', () => {
      //...some code and then:

      expect(error).to.have.type(Error500);
    });

so not sure what I'm missing here.
