Issue:
Currently, when infer schema is being used, for empty array, we are returning NullType. Which causes when the data being written to the destination, instead of Array type, it is being written as String type.
Source data:
"arrayData":[{"properties":[]}]
When written to destination:
"arrayData":[{"properties": ""}]
Fix:
using Array(NullType) instead of NullType for empty array
