Thanks. I tried this workaround. Still, the get_attribute function returns
the value 'none' when used in the first level of inputs. In my case, I am
trying to update the attribute value in one operation using plugin and fetch
the updated attribute value in another operation using the get_attribute
function, for which it returns 'none' when I use SELF as modelable entity.
For the same scenario if I use the node name as modelable entity, it works
fine.

The bug, in case you want to follow its progress:
