How to use the requestretry.defaults function in requestretry

retryStrategy: request.RetryStrategies.HTTPOrNetworkError // (default) retry on 5xx or network errors
    }

    if (parent.options[`${options.type}SocksProxy`]) {
      Object.assign(defaultOptions,
        elasticsearch.applyProxy(url, parent.options[`${options.type}SocksProxy`], parent.options[`${options.type}SocksPort`]))
    }

    if (this.parent.options.tlsAuth) {
      Object.assign(defaultOptions,
        this.applySSL([`${options.type}-cert`, `${options.type}-key`, `${options.type}-pass`, `${options.type}-ca`]))

      Object.assign(defaultOptions, this.applySSL(['cert', 'key', 'pass', 'ca']))
    }

    this.baseRequest = request.defaults(defaultOptions)
  }
