How to use the @faasjs/load.loadConfig function in @faasjs/load

try {
            const ts = await loadTs(cache.file, { tmp: true });
            func = ts.module;

            res.statusCode = 500;
            res.write(error.message);
            res.end();
            return reject(error);
          }
        }
      }
      try {
        if (!cache.handler) {
          // 读取云函数配置并写入缓存
          func.config = loadConfig(this.root, path).development;
          // eslint-disable-next-line require-atomic-updates
          cache.handler = func.export().handler;
        }
