[category- help] .on('end', ...) not waiting till process inside .on('data', ...) is completed.

Nobody has claimed this yet.

here is the flow of code for what i am doing
```
const results = [];
fs.createReadStream('MainVerbs.csv')
.pipe(csv())
.on('data', async function (row) {
await promiseReturningFunction(row['v1'])
.on('end', () => {
console.log('done');
})
```

Problem is that, `.on('end', ...)` end is being fired before the time consuming processing on all rows is done.
I tried using async await in the `.on('data', ...)` section but it didn't make any difference

how do i work with this?

The issue names no repository file or test; start by reproducing the createReadStream().pipe(csv()) chain and its data and end handlers. Check the parser's documented event behavior and establish how completion of asynchronous row processing should be verified; done means the required row work is complete before completion is reported.
