How to use the @hapi/hoek.escapeJson function in @hapi/hoek

payload = JSON.stringify(payload, replacer, space);
                }
                else {
                    payload = JSON.stringify(payload);
                }
            }
            catch (err) {
                throw Boom.boomify(err);
            }

            if (suffix) {
                payload = payload + suffix;
            }

            if (escape) {
                payload = Hoek.escapeJson(payload);
            }
        }

        this._payload = new internals.Response.Payload(payload, this.settings);
    }
