unable integrate dynamic schemas with initial data

I am trying to create a form in which I require the array to have a dynamic schema for a certain field. I tried this by combining http://brutusin.org/json-forms/#3 and http://brutusin.org/json-forms/#0 , the schema,
data and resolver for which are [here](https://pastebin.com/geGna6K9).

Am I doing it wrong ? Is there any alternate way in which I can achieve what I'm trying to do ?
If so please help.
Thanks.

Start with the dynamic-subschemas and initial-data examples linked in the issue, then review the schema, data, and resolver in the referenced Pastebin. Reproduce the attempted form integration and determine whether the behavior is an error or an unsupported combination. Done means documenting the cause and a verified way to handle the dynamic schema with initial data.
