How to update relationship field in entity from UiPath Apps through process as medium

[RpaNoobMax (Akash)]

I am trying to update entity field which is in relationship data type. I m doing by using process as medium. So data type of input argument is object(Application Record)

Input value is coming from UiPath apps dropdown field.
When i Add process as data source in UiPath Apps. In Process inputs it shows object data type like this

So, What should i do to update a value for relationShip type field in Entity. when i pass selected dropdown id as value. i get following error,
Error: Insert or update entity DeveloperManagement data failed. Required field ForApplication cannot be set to null.

Thanks

@RpaNoobMax ,

Are you doing correct mapping while calling process into apps?

you make sure you pass the selected value from drop down and based on that value get id from table and then try to insert.

Thanks,
