This error typically occurs when history is not correctly initialized or your component is not wrapped inside a BrowserRouter. Here’s a typical scenario encountered by beginners while using react-hook-form for form handling.

Solution Overview

The key to fixing the issue is to ensure that the component using history is properly integrated with react-router-dom. Below, we will outline the necessary steps for resolving the issue.

Step 1: Ensure React Router Is Setup

Before using history.push, you need to ensure that your main index file is wrapped with BrowserRouter from the react-router-dom library. This allows your application to utilize the routing capabilities.

Key Takeaways

Always wrap your React application in BrowserRouter when you intend to use routing.

Conclusion

By following these steps, you should be able to effectively use history.push for navigation within your React functional components. Being mindful of routing setup goes a long way in avoiding common pitfalls that new developers encounter.
