JSON Limitations using IWS

I have created a RESTful web service using the IWS wizard with JSON as an input parameter.
It works fine when the JSON is small as in the example provided here: https://www.ibm.com/developerworks/ibmi/library/i-rest-web-services-server3/
However, I need to accept a larger file with hundreds of JSON field names and it fails because all the fields are not declared in my RPG program data structure.

This is the error - org.codehaus.jackson.map.exc.UnrecognizedPropertyException

Is it possible to set something like this?: @JsonIgnoreProperties(ignoreUnknown = true) as described here: https://stackoverflow.com/questions/4486787/jackson-with-json-unrecognized-field-not-marked-as-ignorable/7546047#7546047 , or do I need to declare every field name?

Is there a limit on the number of field names that IWS will allow for a JSON file?

Cheers, Troy.
