# On UDP Error

## Overview

![The On UDP Error Node.](/files/Box1L4o2DRvFLocQlxXQ)

**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**](/incari-studio/2024.1/toolbox/overview.md). Please refer to the [**Plugins Editor**](/incari-studio/2024.1/modules/plugins.md) to find out more information.

[**Scope**](/incari-studio/2024.1/toolbox/overview.md#scopes): **Project**, **Scene**.
