Enabling fastRefresh in a CRA project causes an error

[robcaldecott]

I have just upgraded to SB 6.1.5 and am trying to enable fast refresh in my CRA 4.0.1 project. My main.js looks like this:

module.exports = {
  addons: [
    "@storybook/preset-create-react-app",
    "@storybook/addon-essentials",
    "@storybook/addon-a11y",
  ],
  stories: ["../src/**/*.stories.js"],
  reactOptions: {
    fastRefresh: true,
    strictMode: true,
  },
};

However, starting Storybook gives the following error:

ERROR in ./.storybook/storybook-init-framework-entry.js
Module build failed (from ./node_modules/react-scripts/node_modules/babel-loader/lib/index.js):
Error: Duplicate plugin/preset detected.
If you'd like to use two separate instances of a plugin,
they need separate names, e.g.

  plugins: [
    ['some-plugin', {}],
    ['some-plugin', {}, 'some unique name'],
  ]

Duplicates detected are:
[
  {
    "alias": "/Users/<me>/Projects/digital-workshop/node_modules/react-refresh/babel.js",
    "dirname": "/Users/<me>/Projects/digital-workshop",
    "ownPass": false,
    "file": {
      "request": "/Users/<me>/Projects/digital-workshop/node_modules/react-refresh/babel.js",
      "resolved": "/Users/<me>/Projects/digital-workshop/node_modules/react-refresh/babel.js"
    }
  },
  {
    "alias": "/Users/<me>/Projects/digital-workshop/node_modules/react-refresh/babel.js",
    "dirname": "/Users/<me>/Projects/digital-workshop",
    "ownPass": false,
    "file": {
      "request": "/Users/<me>/Projects/digital-workshop/node_modules/react-refresh/babel.js",
      "resolved": "/Users/<me>/Projects/digital-workshop/node_modules/react-refresh/babel.js"
    }
  }
]

Am I missing something?

CRA enables fast refresh by default so you don't need to enable fast refresh for storybook

Huzzah!! I just released https://github.com/storybookjs/storybook/releases/tag/v6.1.8 containing PR #13303 that references this issue. Upgrade today to the @latest NPM tag to try it out!
