Hey @ssssmy! I'm Dosu, a bot here to help you with bug fixes, questions, and becoming a contributor. Let's squash those bugs together! 🤖

The error ReferenceError: window is not defined indicates that there is an attempt to access the window object in a server-side context, which is not available. This is a common issue when using browser-specific APIs in server-rendered pages.

To resolve this, you should:

  1. Check for Direct References to window: Ensure that there are no direct references to the window object within the /tools page or its components .

  2. Use Client-Side Only Logic: If you need to use the window object, make sure to wrap the code in a check to ensure it only runs on the client side. For example:

    if (typeof window !== 'undefined') {
    // Your code that uses window
}

  3. Custom Hooks: Verify if any custom hooks used in the /tools page are accessing the window object and ensure they are also wrapped in client-side checks .

  4. Next.js Configurations: Review any custom Next.js configurations or plugins that might affect the server-side rendering process for the /tools page .

  5. Environment Variables: Check if there are any specific environment variables or configurations in the .env.local file that might affect the rendering behavior of the /tools page .

By addressing these points, you should be able to resolve the window is not defined error during the build process.
