I have similar issues when I add fields to my structure.
To fix this I manually go through each ‘unknown structure’ error, delete structure-related nodes and make them again
This job is hideous so I refrain from altering my sturcture without absolute necessity

If someone knows how to prevent this error, please tell because I really gotten tired of this.

Add a variable to your struct, then remove it. This generally fixes the problems. Also do a “Refresh Nodes for External Changes” in your blueprints that contains those structs.

Try this, it’s easier than trying to manually find all the culprit nodes:

This worked! Make sure to go through each graph and click it. For example, if you use the struct in a Widget BP and use it in 3 functions for things to be visible, go to each function and the main Event Graph and that fixes it!

Thank you, thank you! You saved my day!

Thank you!!! You deserve a knighthood, my friend.

Add a variable to your problem struct, then add a variable there and delete that. compile your blueprint and then export that. It will work. It work for me

Thanks for this, been using the engine for years, and never knew you could refresh all nodes. Saved my hours of turmoil :wink: Still learning something new each day

Heh, I would love to see the solution, but the image you have shared is not available…

18

Me too

I got another error message as this

Error: ProxyFactoryClass null in K2Node_AsyncAction

Your solution works on my case too!! Glad to have found this section!!

This worked! Thank you!!!

This works, but you have to do it in every BP that you updated members of array or something…
