map循环里async更新数据报异常

按照文档里面写法，执行如下云函数，目的是更新文档的浏览数量

const cmd = db.command;  
const collection = db.collection('goods');  
let data=await collection.get()；  
    data.data.map(async (item) => {  
                    return await collection.doc(item._id).update({  
                    visite: cmd.inc(1)  
                });  
                });

一直提示错误信息

[goodsInfo/ac14109b1588403839929731174/10ms/ERROR] (node:10) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error  
[goodsInfo/ac14109b1588403839929731174/10ms/ERROR] (node:10) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

然后按照网上的说法，可以吧这个异常捕获到

process.on('unhandledRejection', (reason, p) => {  
      console.log('Unhandled Rejection at:', p, 'reason:', reason);  
      // application specific logging, throwing an error, or other logic here  
    });

下面是捕获到的信息
