LogStash JDBC input Error - sqlanywhere - Sybase - undefined method `new


#1

I have been trying to use the JDBC input plugin to connect to my Sybase database (running on a SUSE server) and I think that I have it close but it is throwing a strange error at the moment:

[2018-05-23T00:47:43,415][ERROR][logstash.inputs.jdbc     ] Unable to connect to database. Tried 1 times {:error_message=>"NoMethodError: undefined method `new' for #<Array:0x6b29b1a4>"}

[2018-05-23T00:47:43,416][ERROR][logstash.pipeline ] A plugin had an unrecoverable error. Will restart this plugin.

Here is the full stack trace that loops over and over again:

[2018-05-23T00:51:39,594][ERROR][logstash.inputs.jdbc     ] Unable to connect to database. Tried 1 times {:error_message=>"NoMethodError: undefined method `new' for #<Array:0x6b29b1a4>"}

Here is the basic configuration that I am running for the input:
input {
jdbc {
# Postgres jdbc connection string to our database, mydb
jdbc_connection_string => "jdbc:sqlanywhere://localhost:2638/BI4_Audit"
# The user we wish to execute our statement as
jdbc_user => "user"
# The path to our downloaded jdbc driver
jdbc_driver_library => "/opt/sap/sqlanywhere/java/sajdbc4.jar"
# The name of the driver class for Postgresql
jdbc_driver_class => " "
# Add the password for the DB user
jdbc_password => "password"
# Add a schedule (run every 5 minutes)
#schedule => "30 * * * * *"
# our query
statement => "SELECT * from dba.ADS_EVENT"
}
}

I have gotten past the driver class errors which I had before but am not sure about this undefined method `new

Help is appreciated

I have seen this error in a few threads, however the moderators just seem to let it close.

I know it is not as simple as postgres or mySQL connections but has anyone in the last 2 years been able to at least figure out why this error always appears?
