public final Call<V> handleError(ErrorHandler<V> errorHandler) {
    return new ErrorHandling<>(errorHandler, this);
  }
Returns a call which can attempt to resolve an exception. This is useful when a remote call
returns an error when a resource is not found.

<p>Here's an example of coercing 404 to empty:
<pre>{@code
call.handleError((error, callback) -> {
  if (error instanceof HttpException && ((HttpException) error).code == 404) {
    callback.onSuccess(Collections.emptyList());
  } else {
    callback.onError(error);
  }
});
}</pre>
