[solved] NotFoundError: The object can not be found here.
As developers, we often face situations where our applications throw unexpected errors. One such recurring error is the notorious "NotFoundError: The object cannot be found here." The appearance of such an error message in the console is no less than a mini-heartache for React developers. However, fear not! In this article, we will uncover the common causes of this error and provide methods to diagnose and solve it in your React app.
This is Why NotFoundError Occurs in React Apps
The NotFoundError occurs when an object, component, or file is referenced but cannot be located. In React applications, this error typically stems from various factors such as:
- Incorrect file paths
- Typos in component names, file names, or export/import statements
- Components not being imported/exported correctly
- Deleted files or components still being referenced
- Router issues in your application
Now that we understand some potential causes, let’s explore each of these factors in greater detail.
Incorrect File Paths
Improper file paths are one of the most common reasons behind the NotFoundError. When importing components or assets within a React application, you must provide the correct relative or absolute paths. Mistakes in the file paths can lead to a missing or unresolvable reference, causing the error.
The solution:
- Double-check your file paths and ensure they reference the desired file or component correctly.
- Use JavaScript or TypeScript’s auto-import features, which can help ascertain the correct paths to a file you are referencing.
Typos in Component Names, File Names, or Export/Import Statements
Another frequent cause of NotFoundError is typos. It’s easy to overlook a typographical error in file names, component names, or import/export statements.
The solution:
- Review your code to identify typos and discrepancies.
- Utilize code editors like Visual Studio Code or WebStorm that offer error-checking, auto-completion, and syntax highlighting, which can assist in spotting discrepancies.
Components Not Being Imported/Exported Correctly
Developers frequently encounter NotFoundError due to incorrect export or import statements when dealing with component structures in React apps.
The solution:
- Ensure your components utilize the correct export statement, such as
export default ComponentName;
or export { ComponentName };
.
- During import, write the corresponding import statement that aligns with your export method. For default exports, use
import ComponentName from './ComponentName';
. For named exports, use import { ComponentName } from './ComponentName';
.
Deleted Files or Components Still Being Referenced
In many cases, a file or component might have been deleted, yet its references and imports are still present in the codebase, leading to the NotFoundError.
The solution:
- Use your code editor’s search functionality to locate all instances of the deleted component in the codebase.
- Remove or replace the dead references with the appropriate components or files.

Router Issues in Your Application
Errors in your routing configuration can also trigger the NotFoundError. In React applications, libraries like React Router are used to handle routing and managing different views and URL paths.
The solution:
- Examine your routing configuration and address any errors or inconsistencies.
- Ensure components are assigned and configured correctly with their respective routes.
How To Make NotFoundError a Thing of the Past: Debugging Tips
The aforementioned solutions form a robust foundation for resolving the infamous NotFoundError in your React applications. However, in some instances, these errors can persist even after applying the aforementioned remedies. Fortunately, the following debugging tips can help you trace the root cause of the error:
- Inspect element: Leverage your browser’s developer tools to inspect DOM elements and examine any issues associated with the component in question.
- Console log: Insert
console.log()
lines throughout your code, which can help pinpoint the exact location of the error.
- Create custom error messages: Customize error messages to provide more explicit information regarding code failure.
- Trace component hierarchy: Investigate the hierarchy of components to find any discrepancies or missing relationships.
