I am getting config error while launching Logstash. I am using 7.5.1 version.  
Same config file worked earlier. I had to setup ELK stash on another VM since older VM was decommissioned, and I am facing this error here.

**I'm instantiating logstash using -**

> logstash-7.5.1\bin\logstash -f logstash-config.conf

# config file

```
#config file

input{
jdbc{
jdbc_driver_library=>"C:\software\ojdbc7.jar"
jdbc_driver_class=>"Java::oracle.jdbc.driver.OracleDriver"
jdbc_connection_string=>"jdbc:oracle:thin:@<host>:1528:TSTIM"
jdbc_user=>"UName"
jdbc_password=>"PWD"
statement=>"SELECT * from TABLE where run_id > 4500"
}
}

output{
elasticsearch{
hosts=>"http://localhost:9200"
index=>"run_id"
document_type=>"TABLEname"
document_id=>"run_id"
user=>"elastic"
password=>"changeme"
}
stdout{
codec=>rubydebug
}
}

```

**Error:**

My bad. The config file had some bad characters. I just had to cleanup.  
Handtyping the same content onto another file worked.
