TypeError: axios.get is not a function?

Not sure why I'm getting the following error:

TypeError: axios.get is not a function

    4 |
    5 | export const getTotalPayout = async (userId: string) => {
  > 6 |   const response = await axios.get(`${endpoint}get-total-payout`, { params: userId });
    7 |   return response.data;
    8 | };
    9 |

My service:

import * as axios from 'axios';

const endpoint = '/api/pool/';

export const getTotalPayout = async (userId: string) => {
  const response = await axios.get(`${endpoint}get-total-payout`, { params: userId });
  return response.data;
};

My jest test:

// import mockAxios from 'axios';
import { getTotalPayout } from './LiquidityPool';

const userId = 'foo';

describe('Pool API', () => {
  it('getTotalPayout is called and returns the total_payout for the user', async () => {
    // mockAxios.get.mockImplementationOnce(() => {
    //   Promise.resolve({
    //     data: {
    //       total_payout: 100.21,
    //     },
    //   });
    // });

    const response = await getTotalPayout(userId);
    console.log('response', response);
  });
});

In the src/__mocks__/axios.js I have this:

// tslint:disable-next-line:no-empty
const mockNoop = () => new Promise(() => {});

export default {
  get: jest.fn(() => Promise.resolve({ data: { total_payout: 100.21 }})),
  default: mockNoop,
  post: mockNoop,
  put: mockNoop,
  delete: mockNoop,
  patch: mockNoop
};
