Can you please try using selection parameter in the query entity and try if its at least fetching few column values? How many fields do we have in the CDT? Have you used @Transient annotation in the XSD?
So usually this happens because of multiple reasons . try below methods to identify and resolve the issue 1) pass the paging info with less batch size ( too much data may cause the issue)
2) use query selection to debug and add querycolumn() incrementally and see which column causes the issue. ( invalid datatype, invalid data, complex xsd). Since its a new column , I am betting on wrong datatype or wrong data.
If the configuration is present in XSD, check for the value for the nullable attribute.
