Error Handling

All services return a standard Promise-based response, so the error handling is straightforward:

xg.recommend.getResultsById({elementId: '<element_id>'}).then((result) => {
  // success...
  console.log('Result:', result);
}).catch((error) => {
  // error...
  console.log('Error:', error);
});

// OR if you are using the async/await syntax:

try {
  const result = await xg.recommend.getResultsById({ elementId: '<element_id>' });

  console.log('Result:', result);
} catch (error) {
  console.log('Error:', error);

}

The response error is normalized and always returned as ResponseError object with the following public fields that you could use:

ResponseError {
  url: string, // requested url
  status: number, // response status code
  response: { ... }, // the API JSON error response
  isAbort: boolean, // is abort/cancellation error
  originalError: Error|null, // the original non-normalized error
}
