# Limite d'erreur

Isolez les composants défaillants dans les applis PowerShell Universal avec New-UDErrorBoundary pour empêcher qu'une seule erreur ne fasse planter toute la page.

Le composant `New-UDErrorBoundary` sert à isoler des portions d'un tableau de bord afin de contenir les composants susceptibles de générer une erreur. De nombreux composants d'appli utilisent le composant error boundary en interne.

Si vous souhaitez isoler une portion de votre appli pour empêcher que toute la page ne se charge pas, vous pouvez utiliser la syntaxe suivante.

```powershell
New-UDErrorBoundary -Content {
    throw "Oh no!"
}
```

Si une erreur est générée par le contenu, vous verrez une erreur telle que « One or more errors occured ».

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/powershell-universal/fr/applis/components/utilities/error-boundary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
