## Overview

![The On Socket.IO Error Node.](https://2628349686-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fwnv17cpjDin2deSlOz0z%2Fuploads%2Fgit-blob-ad63124e531e0325928426a5efbc87c4974c1d47%2Fonsocketioerrornodereal.png?alt=media)

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

**Socket.IO 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 Socket.IO Error** will not show up in the [**Toolbox**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2023.1/toolbox/communication/overview.md). Please refer to the [**Plugins Editor**](https://docs.incari.com/incari-studio/2023.1/modules/plugins/communication/socketiomanager) to find out more information.

[**Scope**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2023.1/toolbox/communication/overview.md#scopes): **Project**, **Scene**.
