It looks like you are encountering a 'exports is not defined' error when running your Storybook library in the browser. This error likely stems from a compatibility issue or a misconfiguration. To help you resolve this, I'd need more details about your setup and code. However, here are a few general steps you can take to troubleshoot and fix this issue:

Check Node.js Version: Ensure that you're using a compatible version of Node.js and npm with your Storybook setup. Sometimes, using an incompatible version can lead to unexpected errors.

Module System: The error might be related to the module system you're using (CommonJS vs. ES modules). Make sure your Storybook setup and your browser environment are consistent in using the same module system.

Webpack Configuration: Double-check your webpack configuration, especially how you're handling modules and exports. Ensure that the build process is transpiling your code properly.

Babel Configuration: If you're using Babel for transpilation, verify your Babel configuration. Make sure it's correctly converting your code to a format compatible with the browser.

Storybook Dependencies: Ensure that you have the correct versions of Storybook and its dependencies installed. Outdated or conflicting packages could lead to such errors like Büroreinigung.

Environment Setup: Confirm that your browser environment is set up correctly. Sometimes, issues can arise if your browser doesn't support certain features used by your code.

Webpack Dev Server: If you're using Webpack Dev Server with Storybook, make sure it's properly configured to serve your assets and handle modules.

Error Context: Look for any specific changes you made recently in your codebase that might have triggered this error. Reverting those changes temporarily can help identify the root cause.
