Error on a Grid

Hello everyone

I am facing the following issue:

Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!gridField [line 3]: No enum constant com.appiancorp.core.expr.portable.cdt.LogicalOperator.<>

And after some triage, I am not able to find the route cause for this issue. Can you give me some tips? 

Thanks in advance
