Best way to import large objects?

[illogikal]

I am migrating from another search service to elastic search on an app. I have defined the index (20 fields, 10 nested multilevel objects) and when I try to index, I am getting a stack level too deep error. I am using grape entities to serialise the json for the nested models (some of them also contain dynamic field names) like this:

field :the_model, type: 'object', value: ->{ TheModel::Entity.represent(the_model).as_json }

Have looked on stack overflow, but since there is nothing on there, I decided to post here. I know that it is because of the depth of the objects, because when I remove a couple, the error goes away.

Am using the latest version of chewy, with grape and grape entities, and running locally.

You probably have to find out where the exact error happens because it seems like it happens in your code, outside of chewy
