I'm trying to upload a csv file via logstash and end up with this error. Any Solutions? Here is my logstash.conf file:

> input {  
> file {  
> path =\> "/home/sarthak/Downloads/day.csv"  
> start\_position =\> "beginning"  
> sincedb\_path =\> "/dev/null"

```
}

}
filter {
csv {
separator=>","
    columns=>["Type","Severity","Host Name","timestamp","Message","Machine Name","Path","Score","Data"]
}

}

output {
 elasticsearch {
 hosts => "http://localhost:9200"
 index => "day"
}
stdout {}
}

```
