Rule 'l' has 1 parameters, but instead passed 0 parameters

Hi, i am getting below error

"Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error in rule 'poc_displaycustdetailsgrid' at function a!gridLayout : Rule 'l' has 1 parameters, but instead passed 0 parameters."

It says "Rule 'l' has 1 parameters, but instead passed 0 parameters." But I am not using any rule named 'l'.

Can you please help.
