Csv filter don't work in realtime

[elk2 (piter)]

I send a csv file with filebeat to logstash but csv filter plugin fails when it tries to parse csv with error "unclosed quoted field on line 1"
If I save csv in file with logstash and with another conf I use csv filter on saved file it works correctly.
I use an old logstash version (2.4) and I simply use this:

input{
beat{
port =>5044
}
}
