Fail to update URL field Deluge script

Fail to update URL field Deluge script

Hi there, i need your help.
i'm trying to update through custom function script a field called website which is of a URL type.
Not only it fails, but while debugging it i see that some fields doesnt exist in the map object returns when i call the zoho.crm.getRecordById function. one of them is the Website field, other is the State and City fields.

Why it happens and how do i handle it?

Thanks!
