    Class HttpError

    Error thrown when an HTTP response has a non-2xx status. Carries the numeric status so callers can branch on it (e.g. retrying a 403 WAF cookie challenge) rather than string-matching the message.

    The HTTP status code (e.g. 403)

    The HTTP status text (e.g. "Forbidden")

    The HttpError instance

    try {
      await fetchDecorator(url);
    } catch (error) {
      if (error instanceof HttpError && error.status === 403) {
        // retry the request
      }
    }

    Source

    export class HttpError extends Error {
      public readonly status: number;
      public readonly statusText: string;
      constructor(status: number, statusText: string) {
        super(`HTTP Error: ${status} ${statusText}`);
        this.name = "HttpError";
        this.status = status;
        this.statusText = statusText;
      }
    }
