See the values in nodes

How do you see the values in nodes. Is there a node you connect to see the output, for example a list node similar to grasshopper?. See image if unclear. I want to be able to read the green output .

I find this vital to track what went wrong in complex visual programming.
Also, Print String node and Draw Debug String is NOT working. I’ve seen many posts here about this problem and there are no good answer that lists all possible reasons why this occur. Is this still a bug in 4.21 ?

You can watch all selected values in the debug tab of the blueprint

[Blueprint Debugging | Unreal Engine Documentation][2]

is this something that could help you?

Yes, this seems to be the closest you get in UE4. Thank you!
