Elasticseach filter on logstash not working?

Hi,

I'm trying to use the elastic search filter on logstash for make some Data Enrichment.

I got two indexes, and my goal it's get some data from one of them and add it to the other.

I configured a logstash filter who search in my elasticsearch and if there is a match the output goes to the index.

But my filter it's not working propery because when I test the filter i got this error

[WARN ] 2020-10-02 19:23:09.536 [[main]>worker2] elasticsearch - Failed to query elasticsearch for previous event {:index=>"logstash-*", :error=>"Unexpected character ('%' (code 37)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n

here it's my settings and files

Thanks!
Greetings!
