maybe, this is the problem in last merge

I am running into the same issues. We moved back to Storybook 7.4.3 for the time being.

+1, Seeing same issues.

For me, would work fine with:

addons: ['@storybook/preset-create-react-app', '@storybook/addon-essentials'],

But as soon as I added @storybook/addon-a11y, it would break.

addons: ['@storybook/preset-create-react-app', '@storybook/addon-essentials', '@storybook/addon-a11y']

I wonder if we are all using the a11y addon... I just removed it from our 7.4.4 branch and it's working fine now.

Happening to me as well. Having to revert back to previous version 😢

Same, removing @storybook/addon-themes/@storybook/addon-styling helps.

+1, Seeing same issues. This is “main.ts” in my project.

import type { StorybookConfig } from "@storybook/react-webpack5";
const config: StorybookConfig = {
  stories: ["../src/**/*.mdx", "../src/**/*.stories.@(js|jsx|ts|tsx)"],
  addons: [
    "@storybook/addon-links",
    "@storybook/addon-essentials",
    "@storybook/addon-interactions",
    {
      name: '@storybook/preset-create-react-app',
      options: {
        craOverrides: {
          fileLoaderExcludes: ['less']
        }
      }
    },
    {
      name: '@storybook/addon-coverage',
      options: {
        istanbul: {
          include: ['**'],

    },
    {

      options: {
        less: {
          // Require your Less preprocessor here
          implementation: require('less')
        }
      }
    }, "@storybook/addon-mdx-gfm"],

Yes, got the same error when adding addon-a11y.

Thank you so much for your support @yannbf ! 🙏

[shilman]

We're having some problems getting a release out, so until we do please pin your dependency to 7.4.3. Thank you for your patience!

[shilman]

Ok hopefully fixed in https://github.com/storybookjs/storybook/releases/tag/v7.4.5. Thanks @yannbf !

[Kosai106]

@shilman I just spun up a new Storybook and I'm still having this issue on 7.4.5 as soon as I add addon-a11y 😢

Edit: Nevermind, I updated my addons but not Storybook itself... 🤦‍♂️ False alarm.
