CSV Filter - Quote character causing _csvparsefailure

Curious to know where we place, this code. Reason of asking this question is:-
If we place the code in filter section after mentioning the column(refer my below my logstash.config), it throws an error.

Can we place it before column field ? if yes, please share the sample.

@Makra

mutate {
gsub => ["message", """, " "]
}

Piece of my logstash.config file
filter{

   csv {
 	separator => ","
#	skip_empty_columns => true
	columns => [ "Month", "Quarter", "Year", "INCIDENT_ID" , "RESOLUTION",  "SUMMARY"]
    }
	mutate {convert => ["Month", "integer"]}
	mutate {convert => ["Quarter", "integer"]}
  	mutate {convert => ["Year", "integer"]}
  	mutate {gsub => ["RESOLUTION", "['"\\]","0"]
	mutate {gsub => ["SUMMARY", "['"\\]","0"]
}
