Error in UiPath Action Apps

I am creating a simple process in studio web and creating an apps task for human validations. it works fine when I run the process in studio web, but in unattended, it throws this error. could someone help me with it.

Hi @Anjani_Kapoor

How are you passing the Verification Details to be displayed? Could you show that?

Hi @Anjani_Kapoor,

One of the expressions on the main page or trigger of task might be wrong Please check the same.

Hi @V_Roboto_V , Thank you for responding. below is the screenshot for your reference. I am passing the value using an input argument from studio to Action properties.

Hi @Anjani_Kapoor

Okay. That seems fine.

How are you passing it in Studio? Could you show me that.
If you are concatenating some values of Non-String Types to a string without properly parsing, you might face such issues.
