Struct returns an array with lenght 0

I will try to be very fast. I have a bp_quest actor that has a struct s_questinfo (name, category, etc) with an array of objectives for that quest (each of them are an struct). And the struct of the objective has an array with the dialogues to show by an NPC if it is a “Talk to x NPC” objective. The problem is that when i access the array of the dialogues to give it to the return node of the fuction that is connected to the NPC i have seen that the lenght is 0 with a print string, but the array of dialogues are well configured in the quest…

If you need some photos to see it better i will post it, no problem.
Any solution?

Bye!
