"Failed to derive xcontent" - elasticsearch-ruby/dsl

Elastic Stack Elasticsearch

Hello!

I'm getting the following error when attempting to a run a query from a Rails app -

2016-12-12T17:33:08.461564758Z app[web.4]: --> GET my-lovely-index/_search {} {"aggregations":{"items":{"nested":{"path":"items"},"aggregations":{"name":{"terms":{"field":"items.name","size":1000000}}}}}}
2016-12-12T17:33:09.959661891Z app[web.4]: --> RESPONSE {"error":{"root_cause":[{"type":"parse_exception","reason":"Failed to derive xcontent"}],"type":"parse_exception","reason":"Failed to derive xcontent"},"status":400}

I can copy the query from the logs and run it via the Dev Console/Sense and it runs fine.

I've tried:

  • Removing the size param
  • bundle update => redeploy
  • App server update/bounce
  • Cluster reprovisioning/memory increase

The ES Ruby DSL code looks like:

query_definition = search do
  aggregation :items do
    nested do
      path nested_fields
      aggregation :name do
        terms do
          field field_name
        end
      end
    end
  end
end

terms_response = client.search index: index, body: query_definition.to_json

Cluster in question is: a49768

Any clues as to where I've gone wrong are appreciated, thanks! :slight_smile:

Hi @jay-snee,

As this seems to be a Elasticsearch Ruby DSL issue, I can't help you directly with this from the cloud channel. I'll move this to the Elasticsearch channel where users of the Ruby DSL may be able to help you there.
