Field names are case sensitive. data.tasks.data and Data.tasks.Data are different fields.

Also, if [data][tasks] is an array then that remove\_field will not do anything. You need to include the array index in it, or else do something like [this](https://discuss.elastic.co/t/remove-subfield-using-ruby/225055/4).
