I have problems uploading csv data. Each time it failed. I followed the instructions on

> **[Annotated CSV | InfluxDB OSS v2 Documentation](https://docs.influxdata.com/influxdb/cloud/reference/syntax/annotated-csv/)**
>
> InfluxDB and Flux return query results in annotated CSV format. You can also read annotated CSV directly from Flux with the csv.from() function, write data to InfluxDB using annotated CSV and the influx write command, or upload a CSV file in the UI.

even the example on that page fails

```auto
#group false,false,false,false,false,false,false
#datatype measurement,tag,tag,field,field,ignored,time
#default ,,,,,,
m,cpu,host,time_steal,usage_user,nothing,time
cpu,cpu1,host1,0,2.7,a,1482669077000000000
cpu,cpu1,host2,0,2.2,b,1482669087000000000

```

But the question is why?

Can you provide more details about the failure? Are there any error messages, do some values get written but not others, does the client crash, does the database crash, etc.?
