# Class: StatusCodeError

Defined in: [api.ts:196](https://github.com/coda/packs-sdk/blob/b2b4c9dba5ca748bdbb94481cc13b5ca3c328ef6/api.ts#L196)

An error that will be thrown by [Fetcher.fetch](../../interfaces/Fetcher/#fetch) when the fetcher response has an HTTP status code of 400 or greater.

This class largely models the `StatusCodeError` from the (now deprecated) `request-promise` library, which has a quirky structure.

## Example

```
let response;
try {
  response = await context.fetcher.fetch({
    method: "GET",
    // Open this URL in your browser to see what the data looks like.
    url: "https://api.artic.edu/api/v1/artworks/123",
  });
} catch (error) {
  // If the request failed because the server returned a 300+ status code.
  if (sdk.StatusCodeError.isStatusCodeError(error)) {
    // Cast the error as a StatusCodeError, for better intellisense.
    let statusError = error as sdk.StatusCodeError;
    // If the API returned an error message in the body, show it to the user.
    let message = statusError.body?.detail;
    if (message) {
      throw new sdk.UserVisibleError(message);
    }
  }
  // The request failed for some other reason. Re-throw the error so that it
  // bubbles up.
  throw error;
}
```
