Error while exporting the grid data

Question

Hi, 
 
 We have a code where a view data we are showing in a grid and user have to download the report but while downloading user is getting following error: 
 In the code we are using a user filter on a varchar field because of which there is data issue. 
 Interface Definition: Expression evaluation error [evaluation ID = 325b2:2a9f5] : An error occurred while executing a save: Expression evaluation error at function fn!createfilterfromrecord_appian_internal [line 24]: The passed parameter(s) are of the wrong type. Received the type com.appiancorp.common.xml.JaxbConversionException: error converting typed value TypedValue[it=1980,v={ASSESSMENT MI REPORTs,Assessment Report in MI Reporting,Qm7Kig,{81,,10d2b745-9e94-474d-928a-c623c6e7ca8a@_a-0000eccb-82f8-8000-9c64-011c48011c48_16707690,0},#"SYSTEM_SYSRULES_recordGridField

Check the saveInto code corresponding to the Download action. Looks like some parameter is being passed between objects and there is a data type mismatch between source and target. If you can share a code snippet will be better!

The error shows a complex object (with UUIDs/encoded references) being passed to a VARCHAR field filter. If you're using a user/group picker component to filter text data, Replace picker with a!textField or filter varchar on username strings directly.
