Hi im new to logstash what does this error mean? (version 5.6.8)

Cannot create pipeline {:reason=\>"Expected one of #, {, ,, ] at line 33, column 26

input {  
file { path =\> ["/var/log/collectd.logstash.log"]  
start\_position =\> beginning  
sincedb\_path =\> ["/var/log/collectd/logstash.log"]  
}

```
    udp {
    port => 25828
    buffer_size => 1452
    codec => collectd{ typesdb => ["/usr/share/collectd/types.db"] }

```

}  
}

filter {

```
    if "_grokparsefailure" in [tags] {
    drop { }

     grok {
            match => { "message" => "%{NUMBER:duration}, %{NUMBER:value}, %{DATA:value}, %{WORD:host}, %{IP:client}"}

    add_field => ["received_at", "%{@timestamp}"]

```

# add\_field =\> ["cpu", "%{NUMBER:cpu}"]

# add\_field =\> ["received\_at", "%{@timestamp}"]

# add\_field =\> ["received\_from", "%{host}"]

# add\_field =\> ["value", "%{NUMBER:value} %{DATA:value}"]

```
    add_field => ["test", "%{WORD:test}]

```

}  
}

output {  
file { path =\> ["/var/log/logstash/logstash2.log"] }  
elasticsearch { hosts =\> ["localhost:9200"] }

```
  influxdb {
            use_event_fields_for_data_points => true
            data_points => {}
            host => localhost
            db => collectd
            coerce_values => {"value" => "float"}

```

}

stdout {  
codec =\> rubydebug }

Thnx in advance  
Owusu

The error message means that the Logstash configuration file parser found something unexpected at or near line 33. I'm guessing the problem is that missing quote near the end of this line:

```
add_field => ["test", "%{WORD:test}]
```

Thank you for the response, indeed it was the quotes.  
I have another question but will open a new post for that.

Again thank you
