[Error] Unknown setting 'copy' for mutate

[TaurusD]

• Version: the most updated one cuz I just re-installed it in Logstash 5.4.2

• Operating System: Win 10

• Config File (if you have sensitive info, please remove it):
  mutate { copy=> { "[Longitude]" => "[geo_location][lon]" "[Latitude]" => "[geo_location][lat]" } }

• Sample Data: [Longitude] and [Latitude] are float, and [geo_location] is pre-defined geo_point in Kibana.

I ran this command bin\logstash -f first-pipeline.conf --config.reload.automatic and get:
[2017-07-14T09:57:45,923][ERROR][logstash.filters.mutate ] Unknown setting 'copy' for mutate
[2017-07-14T09:57:45,930][ERROR][logstash.agent ] Cannot create pipeline {:reason=>"Something is wrong with your configuration."}

Hello @TaurusD , the version of the plugin are fixed when packaging logstash, so a re-installation will not fetch the most updated one. You can check a speficic plugin version using
bin/logstash-plugin list --verbose <plugin-name>logstash-filter-mutate
In 5.4.2: this give

bin/logstash-plugin list --verbose logstash-filter-mutate
logstash-filter-mutate (3.1.3)

And the copy option was introduced in next version. You have to manually update the plugin to the latest version with the command bin/logstash-plugin update logstash-filter-mutate and you will be able to use the copy method

bin/logstash-plugin update logstash-filter-mutate
Updating logstash-filter-mutate
Updated logstash-filter-mutate 3.1.3 to 3.1.5
