    Description

      In checkInputColumn, if data types do not match, it tries to print an error message with this in it:

      Column param description: ${getParam(colName)}"

      However, getParam cannot be called on the string colName; it needs the parameter name, which this method is not given. This causes a weird error which users may find hard to understand.
