TypeError: res.once is not a function

Code in the file thats causing the error

 res.once('finish', function () {
                                var transaction = tracing_1.getActiveTransaction();
                                if (transaction) {
                                    transaction.setHttpStatus(res.statusCode);
                                    // we'll collect this data in a more targeted way in the event processor we added above,
                                    // `addRequestDataToEvent`
                                    delete transaction.metadata.requestPath;
                                    // Push `transaction.finish` to the next event loop so open spans have a chance to finish before the
                                    // transaction closes
                                    setImmediate(function () {
                                        transaction.finish();
                                    });
                                }
                            });
