title: Intentionally Throwing an Error in RunJS for Debugging
|
|
---
|
|
|
|
In this step-by-step guide, we'll walk you through the process of creating a RunJS query that intentionally throws an error for debugging purposes.
|
|
|
|
<div style={{paddingTop:'24px', paddingBottom:'24px'}}>
|
|
|
|
### Creating the Error-Throwing RunJS Query
|
|
|
|
1. Create a new RunJS query by clicking the `+ Add` button on the query panel.
|
|
|
|
2. Paste the following code into the RunJS query editor. This code utilizes the `ReferenceError` constructor to intentionally generate an error.
|
|
```js
|
|
throw new ReferenceError('This is a reference error.');
|
|
```
|
|
|
|
</div>
|
|
|
|
<div style={{paddingTop:'24px', paddingBottom:'24px'}}>
|
|
|
|
### Adding an Event Handler for Failure
|
|
|
|
3. Now, enhance the query by adding an event handler that will display an alert when the query fails.
|
|
|
|
4. Click the "Run" button to execute the query and observe the intentional error being thrown.
|
|
|
|
Refer to the screencast below:
|
|
|
|
<div style={{textAlign: 'center'}}>
|
|
<img style={{ border:'0', marginBottom:'15px', borderRadius:'5px', boxShadow: '0px 1px 3px rgba(0, 0, 0, 0.2)' }} className="screenshot-full" src="/img/how-to/failjs/failjsn.gif" alt="reate a new RunJS query" />
|
|
</div>
|
|
|
|
</div>
|
|
|
|
By following these steps, you can effectively simulate errors in your RunJS queries, aiding in the debugging process and improving the overall robustness of your code. |
