Struggling to make axios work with Rollup

I'm trying to get Axios to work in a Rollup environment but I run into the following error whatever I do. I'm also not sure whether I should use axios/index.js or axios/lib/axios.js inside the commonjs plugin configuration.

Uncaught SyntaxError: The requested module '../../../../node_modules/axios/index.js' does not provide an export named 'default'

rollup.config.js

import merge from 'deepmerge';
// use createSpaConfig for bundling a Single Page App
import { createSpaConfig } from '@open-wc/building-rollup';

import resolve from 'rollup-plugin-node-resolve';
import json from 'rollup-plugin-json';
import builtins from 'rollup-plugin-node-builtins';
import globals from 'rollup-plugin-node-globals';
import commonjs from 'rollup-plugin-commonjs';

// use createBasicConfig to do regular JS to JS bundling
// import { createBasicConfig } from '@open-wc/building-rollup';

const baseConfig = createSpaConfig({
  // use the outputdir option to modify where files are output
  // outputDir: 'dist',

  // if you need to support older browsers, such as IE11, set the legacyBuild
  // option to generate an additional build just for this browser
  // legacyBuild: true,

  // development mode creates a non-minified build for debugging or development
  developmentMode: process.env.ROLLUP_WATCH === 'true',

  // set to true to inject the service worker registration into your index.html
  injectServiceWorker: false,
});

export default merge(
  baseConfig,
  {
    // if you use createSpaConfig, you can use your index.html as entrypoint,
    // any <script type="module"> inside will be bundled by rollup
    input: './index.html',

    // alternatively, you can use your JS as entrypoint for rollup and
    // optionally set a HTML template manually
    // input: './app.js',
  },
  {
    input: './node_modules/axios/index.js',
    output: {
      file: './index.js',
      format: 'es',
    },
    plugins: [
      resolve({ jsnext: true, preferBuiltins: true, browser: true }),
      json(),
      globals(),
      builtins(),
      commonjs(),
    ],
  }
