How to use the swagger-client.serializeRes function in swagger-client

module.exports = function({ configs }) {

      resolveSubtree: Swagger.resolveSubtree,
      serializeRes: Swagger.serializeRes,
      opId: Swagger.helpers.opId
    }
  }
}

execute: Swagger.execute,
      resolve: Swagger.resolve,
      resolveSubtree: (obj, path, opts, ...rest) => {
        if(opts === undefined) {
          const freshConfigs = getConfigs()
          opts = {
            modelPropertyMacro: freshConfigs.modelPropertyMacro,
