@notgiorgi I was experiencing this, too. I believe this is due to customization of Storybook’s webpack config. Modification of module rules was messing with storybook’s react-docgen configuration in my case. The fix for me:

 module.exports = (baseConfig, configType) => {
   const isDev = configType === "DEVELOPMENT";
 
   // Resolve to iOS-specific components
   baseConfig.resolve.extensions.push(".ios.js");
 
   baseConfig.module.rules.push(
-    {
-      test: /\.js$/,
-      exclude: /node_modules/,
-      use: {
-        loader: "babel-loader",
-        options: {
-          cacheDirectory: true
-        }
-      }
-    },
     {
       test: /\.(gif|jpe?g|png|svg)$/,
       use: {
         loader: "url-loader",
         options: {
           name: "[name].[ext]"
         }
       }
