How to Fix the ‘Objects are not valid as a React child’ Error in React?

Estimated read time 2 min read

The “Objects are not valid as a React child” error occurs when you try to render an object in your React component instead of a valid React element.

Here are some common causes of this error and ways to fix them:

  1. Trying to render an object directly:

If you try to render an object directly, React will throw this error. You can fix this by converting the object into a valid React element before rendering it. For example, if you have an object called “myObj”, you can use JSON.stringify(myObj) to convert it to a string before rendering it.

  1. Using an object as a child of a React component:

If you use an object as a child of a React component, React will throw this error. You can fix this by converting the object into a valid React element before using it as a child. For example, if you have an object called “myObj”, you can wrap it in a React.Fragment or a div element like this:

<React.Fragment>{myObj}</React.Fragment>

or

<div>{myObj}</div>
  1. Trying to render an array of objects:

If you try to render an array of objects directly, React will throw this error. You can fix this by mapping over the array and converting each object into a valid React element before rendering it. For example:

const myArr = [{name: 'John', age: 25}, {name: 'Mary', age: 30}];

return (
  <ul>
    {myArr.map((obj) => (
      <li key={obj.name}>{`${obj.name} (${obj.age})`}</li>
    ))}
  </ul>
);

In this example, we map over the array and convert each object into a list item element with the person’s name and age.

By following these tips, you should be able to fix the “Objects are not valid as a React child” error in your React application.
