Hi Deepan, The error is due to apply function in the code to get formatted users where there is no data after filtering. In that case to avoid this error you can use '{}' instead of 'null' in your code and it will show a empty grid with 'No items available' message. For example in Analyst column you can use this 'data:apply(rule!getFormattedUserName,index(local!datasubset.data,"Analyst",{})) '.
