Review organization subgraph to prevent undefined and null attributes when possible

[0xGabi]

Having these values undefined or null on the subgraph cascade across the whole codebase. It would be nice low hanging fruit to do a quick review of the subgraph.

@nivida Sure, we can do some investigation. Can you specify the subgraph or list of subgraphs?
