Hi servilienr0001, can you share more information about this error?

In which Appian component is this error happening? Can you share the SAIL code that generates this error?

This error occurs when i try to "View Record List" ..
A user filter has been built and uses a contant containing an array (text)

..new to APPIAN, don't know much about SAIL, sorry !

Hi Pedro,

..thanks for reply

The array constant (4 text literals) is to populate the dropdown as below:

            a!dropdownField(
              label: "Category",
              labelPosition: "ABOVE",
              placeholder: "--- Select a Value ---",
              choiceLabels: cons!VFM_VEHICLE_CATEGORIES,
              choiceValues: cons!VFM_VEHICLE_CATEGORIES,
              value: ri!vehicle.category,
              saveInto: ri!vehicle.category,
              searchDisplay: "AUTO",
              showWhen: or(                              
                isnull(ri!readOnly),                              
                ri!readOnly=false()    
                ),

Hi servilienr0001, please check the following link regarding User Filters in Record Lists (I'm assuming that is your case).
