| Option | Description |
|---|---|
| Standard debug headers | Provides general status and EdgeWorker information (id, version, and name) for the executed EdgeWorkers function. |
| Enhanced debug headers | As a best practice you should enable enhanced debug headers. You can use DataStream 2 to deliver JavaScript logs. For more information go to the Use DataStream 2 to deliver JavaScript logs tutorial. These enhanced debug trace headers provide actionable details that will help you troubleshoot your EdgeWorkers. |
| Error codes - EdgeWorkers Management Application | View a list of error codes that are displayed in the EdgeWorkers Management application to keep you informed about limitations and issues. |

Review these resources and tips that can also help you troubleshoot and test your EdgeWorkers:
- To handle exceptions cleanly write
tryandcatchblocks in your JavaScript code. - Refer to the Limitations section for information about what you should keep in mind when designing your EdgeWorkers functions. You can also review a list of the currently supported delivery products.
- Use Site Failover to define what action to take in the event that an EdgeWorkers function fails.
- EdgeWorkers functions are supported on both the Enhanced TLS and Standard TLS networks.
