AUR0765

Error Message

AUR0765: Trying to retrieve a custom element controller from a node. But the provided node <{{nodeName}} /> does not appear to be part of an Aurelia app DOM tree, or it was added to the DOM in a way that Aurelia cannot properly resolve its position in the component tree.

Where {{nodeName}} is the tag name of the provided DOM node.

Description

This error has the same root cause as AUR0764: Aurelia cannot resolve a controller relationship for the provided node within the current app’s component tree.

Example Trigger

import { CustomElement } from '@aurelia/runtime-html';

// ❌ Node is detached or outside the Aurelia app root
const node = document.querySelector('#outside-the-app')!;
CustomElement.findController(node); // throws AUR0765

Correct Usage

See AUR0764 for guidance on ensuring nodes are Aurelia-managed before attempting controller lookup.
