## Common issues <a href="#common-issues" id="common-issues"></a>

Here are some common errors and issues with the Facebook Lead Ads Trigger node and steps to resolve or troubleshoot them.

### Workflow only works in testing or production <a href="#workflow-only-works-in-testing-or-production" id="workflow-only-works-in-testing-or-production"></a>

Facebook Lead Ads only allows you to register a single webhook per app. This means that every time you switch from using the testing URL to the production URL (and vice versa), Facebook Lead Ads overwrites the registered webhook URL.

You may have trouble with this if you try to test a workflow that's also active in production. Facebook Lead Ads will only send events to one of the two webhook URLs, so the other will never receive event notifications.

To work around this, you can disable your workflow when testing:

{% hint style="warning" %}
**Halts production traffic**

This workaround temporarily disables your production workflow for testing. Your workflow will no longer receive production traffic while it's deactivated.
{% endhint %}

1. Go to your workflow page.
2. From the workflow settings dropdown, click **Unpublish** to disable the workflow temporarily.
3. Test your workflow using the test webhook URL.
4. When you finish testing, click **Publish**. The production webhook URL should resume working.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.n8n.io/integrations/builtin/trigger-nodes/n8n-nodes-base.facebookleadadstrigger.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
