### Problem

As we were doing the symobilse conversion in the environment.rb, it wasn't applied on a batch request as when creating the meta the options hash is passed directly in from the JSON and doesn't come from the query string.

### Solution

Do the conversion `component_meta.rb` so both components (and possibly further adaptions) have the same converted options hash.
