# Troubleshoot the webhook for failed builds or a hanging job
<a name="buildkite-runner-troubleshoot-webhook"></a>

 **Issue: ** 

The webhook you set up in [Tutorial: Configure a CodeBuild-hosted Buildkite runner](sample-runner-buildkite.md) isn't working or your workflow job is hanging in Buildkite.

 **Possible causes: ** 
+ Your webhook **job.scheduled** event might be failing to trigger a build. Review the **Response** logs to view the response or error message.
+ Your CodeBuild build fails before starting the Buildkite self-hosted runner agent to handle your job.

 **Recommended solutions: ** 

To debug failed Buildkite webhook events:

1. In your Buildkite organization settings, navigate to **Notification Services**, select your CodeBuild webhook, and then find the **Request Log**.

1. Find the `job.scheduled` webhook event associated with your stuck Buildkite job. You can use the job ID field within the webhook payload to correlate the webhook event to your Buildkite job.

1. Select the **Response** tab and check the response body. Verify that the **Response** status code is `200` and the **Response** body doesn’t contain any unexpected messages.
