Read a TOPs attributes from SOP

[reyan 2]

Hello folks, 
i'm reading a .json in TOPs, creating string attributes, and collecting.
Now, i would like to read those attributes that i created in TOPs from SOP, i'm tryng with @myattr, and pdginput, but no luck.

Basically it's the same situation described here: https://www.sidefx.com/forum/topic/66408/
 

Any idea ?

Thanks in advance
