Logstash not inserting records in ElasticSearch - elasticsearch

Question

I am trying to insert simple CSV values to ES. it is not going thru.
The conf file i am using is as follows:
input {
file {
path => "D:/ELK/Logs/rahul.csv"
start_position => "beginning"
sincedb_path => "NULL"
}
}
filter {
csv {
columns => [ "record_id", "duration", "src_bytes", "dest_bytes" ]
}
}
output {
elasticsearch {
hosts => "http://localhost:9200"
index => "rahul"
}
stdout {}
}
I checked the error log on Logstash\logs folder. following is there

Answer 1

resolved by adding sincedb_path => "NULL" to the input plugin, like so:
input {
file {
path => "D:/ELK/Logs/rahul.csv"
start_position => "beginning"
sincedb_path => "NULL"
}
}
