Attempted to access index from array of length 0! error
I am getting errors in my blueprint where I set the style for my inventory widget. This is what the error looks like. This is my blueprint.
It won't let me upload the last picture but it is exactly the same as the other picture where the style is being set, it is just attached to the other set style node.
The inventory I set up seems to be working fine, but I get all these errors. Does anyone know how I can fix this, or what causes this error? Also if you need more information I can get it. Thanks!

Ok, so I figured it out. Add some is valid indexs and branches in your flow to solve the issue. I assume this was following the titanic games rpg tutorial series, so check out the UI Inventory Event graph and Set Widget Style Functions respectively if you are following that tutorial.
