buildStoriesJson feature produces error when "stories" is set to async function

[rachelholtz]

In "main.js" I am using an async function to set which story files to load. This works correctly until I add the buildStoriesJson and I get an error.

This is my "main.js" file:

module.exports = {
  stories: async (list) => [...list, ...findStories()],
  addons: [
    '@storybook/addon-links',
    '@storybook/addon-essentials',
    '@storybook/preset-scss',
    '@storybook/addon-a11y',
  ],
  features: {
    buildStoriesJson: true
  },
};

Using @storybook/react@6.5.10

Any update on this?
