**On UDP Error** is an **Event Listener Node** that executes and triggers a **Logic Branch** when an **Error** is received and returns the **Error** `Message`.

**UDP Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **On UDP Error** will not show up in the [**Toolbox**](https://docs.incari.com/incari-studio/toolbox/overview). Please refer to the [**Plugins Editor**](https://docs.incari.com/incari-studio/modules/plugins) to find out more information.

[**Scope**](https://docs.incari.com/incari-studio/overview#scopes): **Project**, **Scene**.
