"Invalid cliet task found" error while filtering Lookup Field values

Hi,

I am encountering an error message, "Invalid clist task found," while trying to filter out the lookup values in Zoho Creator. Here is the script I am using:

clear input.deploymentDate;

availableDates = DeploymentWindows[availableDate> zoho.currentdate].availableDate.getAll();

list = List();

list.add(availableDates);

input.Standard_Deployment_Window:ui.add(list);

The scenario is that I have two forms: one contains the available deployment dates for the entire year, and the other form has a lookup field for these dates.

My goal is to filter out the dates that have passed the current date of the lookup field. However, I am encountering the error.

I suspect there might be an issue with the data type, but I don't have the specific details. I would appreciate any guidance on what could be causing this error and how to resolve it.

Thank you in advance for your assistance!
