title: Intentionally fail a RunJS query
|
|

In this how-to guide, we will create a RunJS query that will throw an error.
|
|
|
|
- Create a RunJS query and paste the code below. We will use the constructor `ReferenceError` since it is used to create a range error instance.
|
|
```js
|
|
throw new ReferenceError('This is a reference error.');
|
|
```
|
|
|
|
- Now, add a event handler to show an alert when the query fails. **Save** the query and **Run** it.

<div style={{textAlign: 'center'}}>

<img className="screenshot-full" src="/img/how-to/failjs/failjs.gif" alt="Intentionally fail a RunJS query" />

</div>
