Csv import no data insert?

Hello Support Team,

I was just trying to load some data via a CSV file. The creation went well without any errors, and it went through successfully. However, when I try to view the bucket, it’s empty, and nothing has been written.

What am I doing wrong???

Here are some example data:

#group,false,false,true,true,false,false,true,true
#datatype,string,long,dateTime:RFC3339,dateTime:RFC3339,dateTime:RFC3339,double,string,string
#default,mean,,,,,,,
,result,table,_start,_stop,_time,_value,_field,_measurement
