new OperationalError(String message) -> OperationalError
Represents an error is an explicit promise rejection as opposed to a thrown error. For example, if an error is errbacked by a callback API promisified through Promise.promisify or Promise.promisifyAll and is not a typed error, it will be converted to a OperationalError which has the original error in the .cause property.
OperationalErrors are caught in .error handlers.
