I am trying to use the CSV filter to read csv file.
First of all, I used an input file plug-in to read the file.
Then, I used CSV to add columns. But I got a very strange error message in the character that follows the CSV filter name which is "{". Even when I tried to use an empty filter like "csv{}" I got the same error 
Could you please advice...?
Here is the configuration file:
file {
path => "/tmp/test-1.csv"
start_position => "beginning"
tags => ["history"]
}
filter
{
csv {
columns => ["lt.si","lt.dm","lt.px","lt.py","lt.pz","lt.sc","lt.as","lt.ap","lt.pn","lt.po","lt.am","lt.ar","lt.apMac","lt.bi","lt.lh","lt.mp","lt.la","lt.lo","lt.created_at"]
}
}
output
{
elasticsearch {
user => elastic
password =>xxxxxx
}
}
Here is the error message:
