ReactJs app with Jest and enzyme throwing error / new tests fail

Please help me get rid of the error below (using jest and enzyme for unit testing for reactjs app)

I'm trying to figure out this error which I get with every new test I add, whatever I try to test (even most basic - if component exists, with the same code which worked with other components before) it throws the same error with every new component. I'm not sure what I changed, but old tests pass and new ones give me this error :

  TypeError: Cannot read property 'options' of undefined

example of test for a random component:

import React from 'react'
import { shallow } from 'enzyme'
import expect from 'expect'
import Session from './index'

describe('<Session />', () => {

    it('exists ', () => {
        expect(shallow (<Session />).length).toEqual(1);
    });

    it("should be on a loading state", () => {
        const wrapper = shallow(<Session />);
        expect(wrapper.state().loading).toEqual(true);
    });

});
