Authsignal Server SDKs can return errors for a variety of reasons, such as invalid requests or network interruptions, which should be handled accordingly. 
const request = {
  userId: "dc58c6dc-a1fd-4a4f-8e2f-846636dd4833",
};

try {
  const response = await authsignal.getUser(request);
} catch (e) {
  if (e instanceof AuthsignalError) {
    const statusCode = e.statusCode;
    const errorCode = e.errorCode;
    const errorDescription = e.errorDescription;
  }
}

​

Error codes

​
invalid_configuration
Indicates that the request cannot be handled because the tenant is in an invalid configuration.
​
invalid_credential

​
invalid_request
Indicates that the request failed due to an invalid parameter or input.
​
too_many_requests
