class RequestError extends Error
```

## Mentioned in

Migrating from Version 5 to Version 6

## Discussion

Discussion When a Service method’s returned promise rejects, the rejection value is a RequestError. The message property contains a ConfigurationErrorStatus value that describes the error. const search = new mapkit.Search();

try {     const data = await search.search("coffee"); } catch (error) {     if (error.message === "Too Many Requests") {         // Handle rate limiting.     } }
