source-loader: TypeError: Cannot read property 'query' of undefined

[petermikitsh]

Describe the bug

An auto-generated storybook with @storybook/source-loader prints this error message and sources do not load, and no 'Story' tab appears.

To Reproduce

Demo Repo: https://github.com/petermikitsh/sb-source-error (just run yarn start-storybook)

Steps to reproduce the behavior:

npx init storybook # choose react
npm i @storybook/source-loader --dev

.storybook/main.js:

module.exports = {
  stories: [
    "../stories/**/*.stories.mdx",
    "../stories/**/*.stories.@(js|jsx|ts|tsx)",
  ],
  addons: [
    "@storybook/addon-links",
    "@storybook/addon-essentials",
+    "@storybook/source-loader",
  ],
+  webpackFinal: async (config) => {
+    config.module.rules = [
+      ...config.module.rules,
+      {
+        test: /\.stories\.jsx?$/,
+        loaders: [
+          {
+            loader: require.resolve("@storybook/source-loader"),
+            options: { parser: "javascript" },
+          },
+        ],
+        enforce: "pre",
+      },
+    ];
+    return config;
+  },
};

Expected behavior

No error, story source code loads.

My apologies-- I may have mis-read the documentation. I think my configuration listed above is incorrect. I've since updated my configuration. Most of my stories are now populating with source code.

Addons should be something like:

  addons: [
    "@storybook/addon-links",
    "@storybook/addon-essentials",
+   "@storybook/addon-storysource",
  ],

@storybook/addon-storysource uses @storybook/source-loader under the hood. If you're overriding webpack configs (e.g defining your own config.module.rules array, you'll need to setup @storybook/source-loader yourself.
