Error Handling For Fetch() In Aurelia

I have an API that includes a useful description of what went wrong when an error is raised by the server (status = 500). The description comes as part of the response text. My cli

Solution 1:

This should do the trick:

functioncallRemoteService(apiName, timeout = 5000) {
  returnPromise.race([
    this.http.fetch(apiName)
      .then(
        r => r.json(),
        r => r.text().then(text =>thrownewError(text))
      ),
    this.waitForServer(timeout)
  ]);
}

by the way, I like what you're doing with Promise.race- nice technique!
