# AUR4107

## Error Message

`AUR4107: GroupRule cannot be executed without a scope.`

## Description

This error occurs when a `GroupRule` is executed without the required `scope` context.

## Example Trigger

This is typically caused by calling low-level rule execution APIs without providing a validation scope.

## Solution

* Execute group rules via the standard validation pipeline (for example via a `ValidationController`) so the scope is provided.
* If you are using lower-level APIs, ensure you pass a valid scope when executing rules.

## Troubleshooting

* Check where the rule is executed and verify a scope is available and passed through.
* Prefer higher-level validation APIs unless you are building a custom validation integration.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.aurelia.io/developer-guides/error-messages/4100-to-4106/aur4107.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
