描述

Describe the bug

When adding a new story to a stories file that is imported in a .mdx file, the following error is thrown:

Invalid value passed to the 'of' prop. The value was resolved to a 'component or unknown' type but the only types for this block are: story.

It happens when the imported story files is modified in other ways as well, but this is the most simple case to replicate this bug.

Reproduction link

https://stackblitz.com/edit/github-unrkza-3cuztn?file=src%2Fstories%2FButton.stories.ts

Reproduction steps

Go to the link above
Open "Buttons documentation" doc in the preview pane
Open src/stories/Button.stories.tsx file
Duplicate e.g. the Secondary story and rename it to e.g. Tertiary

Expected behavior: The doc is still rendered correctly.

Actual behavior: The error mentioned above it thrown.

System

I'm not sure how to run `npx storybook@latest info` on StackBlitz, as the terminal does not seem to work for me. I am using the React 18 Webpack template, which uses Storybook 8.4.0-alpha.0.

Additional context

It makes writing documentation using MDX files a bit frustrating ;)

贡献者指南

研究方向: Investigate the codebase of storybookjs/storybook, focusing on how MDX files are processed and how story imports are resolved during hot module replacement. Look at the relevant core addon for docs and the MDX compiler. The error suggests a type mismatch in the 'of' prop for story blocks. Examine the code path when a stories file changes and how the story metadata is updated. Check existing issues or PRs related to MDX and story import updates.
