How to Fix “Objects Are Not Valid as a React Child” Error Easily

Understanding the “Objects Are Not Valid as a React Child” Error

If you’re seeing the error message “Objects are not valid as a React child”, it means you’re trying to render a JavaScript object directly inside your JSX. React doesn’t know how to display raw objects. It expects strings, numbers, or valid React components—not plain objects.

Why This Error Happens

Here’s a common example that triggers this error:

{JSON.stringify({name: "React"})} // ✅ Correct
{ {name: "React"} } // ❌ Triggers the error

React can’t render an object directly inside curly braces. It needs a string representation of that object, or you need to render its individual properties.

How to Fix the Error

There are a few ways to fix this error depending on what you’re trying to achieve:

  1. Use JSON.stringify() to convert the object to a string: 
    {JSON.stringify(myObject)}
  2. Render individual object properties: 
    {myObject.name}
  3. Conditionally check for object types: 
    {typeof myObject === 'object' ? JSON.stringify(myObject) : myObject}

Real-World Use Case

Let’s say you’re building a user card and trying to render the user object directly:


const user = { name: 'John', age: 30 };

// ❌ This will throw the error
return <div>{user}</div>

// ✅ This will work
return <div>{user.name} - {user.age}</div>

Best Practices to Avoid This Error

  • Always double-check the type of data you’re rendering in JSX.
  • Use developer tools or console.log to inspect what your variable contains.
  • Don’t directly render complex objects. Break them down or stringify when needed.

Still Confused?

If you’re still running into issues, take a look at where your object is coming from. It might be returned from an API, a Redux state, or passed down as a prop. Wherever it originates, make sure you’re only rendering what React understands—strings, numbers, arrays of elements, or components.

Wrapping Up

The “objects are not valid as a React child” error in React is quite common and easy to fix once you understand what JSX can and cannot render. Focus on extracting the data you need or converting it into a string when necessary.
