Issue encountered while extracting data using CDATA JDBC driver in Snaplogic. Specifically, we are receiving the following error message:

“Class java.lang.Boolean cannot be cast to class java.lang.Number (java.lang.Boolean and java.lang.Number are in module java.base of loader ‘bootstrap’)”

Thanks
