multiline field in csv (logstash) - elasticsearch

Question

I am trying to make the multiline field for csv file work in logstash.
But the multiline for a field is not working.
My log stash.conf content is:
input {
file {
type => "normal"
path => "/etc/logstash/*.csv"
start_position => "beginning"
sincedb_path => "/dev/null"
codec => multiline {
pattern => "."
negate => true
what => "previous"
}
}
}
filter {
if [type] == "normal" {
csv {
separator => ","
columns => ["make", "model", "doors"]
}
mutate {convert => ["doors","integer"] }
}
}
output {
if [type] == "normal" {
elasticsearch {
hosts => "<put_local_ip>"
user => "<put_user>"
password => "<put_password>"
index => "cars"
document_type => "sold_cars"
}
stdout {}
}
}
.csv with multiple line (in quotes) for a field make is:
make,model,doors
mazda,mazda6,4
"mitsubishi
4000k", galant,2
honda,civic,4
After I run "logstash -f /etc/logstash/logstash.conf"
I am getting parse failure, from the logs:
{
"tags" => [
[0] "_csvparsefailure"
],
"#timestamp" => 2020-07-13T19:13:11.339Z,
"type" => "normal",
"host" => "<host_ip_greyedout>",
"message" => "\"mitsubishi",
"#version" => "1",
"path" => "/etc/logstash/cars4.csv"
}
