What type do I use for when the API returns an error?

[captbunzo]

I am writing an application using this lovely library and am attempting to improve my error handling. When I am attempting to retrieve a user, a successful response can be interpreted as APIUser.

However, I am having trouble identifying what error to use when interpreting an error like this. Any tips?

Response {
    status: 401,
    statusText: 'Unauthorized',
    headers: Headers {
      date: 'Thu, 25 Sep 2025 00:12:40 GMT',

  }```

You're probably looking for the RESTError type
