How to validate a "Blueprint Session Result Structure" variable?

[KingKerel]

I am working on hosting/joining multiplayer sessions.
I made a custom event (JoinSession) which requires an input of “Blueprint Session Result Structure”.
This input is a result from the array gained from the “Find Sessions” node.
Before I use this variable in further nodes, I would like to validate it.
However the normal “Validate” does not work on this.
Also a “Split Struct” or “Breakout” does not work on this.
It does tell me “Cannot split the struct pin, it may be missing Blueprint exposed properties!”.

So how do I validate this variable?

I still don’t know a solid solution to this obstacle.
But I guess I found a workaround by testing the ServerName variable against an empty string.
Best I can come up with.

Anybody have a better idea?
