Can not implement NiagaraDataInterface

I try to implement Niagara Data Interface, but it does not work. I always have errors. I read this topic, investigated some external examples in github and some examaples that exist in EU5 sources.

After that i did my custom DataInterface and it does not work, so i just did copy past of existing solution(just for checking) and it is has same errors and does not work. I can not build it.

Could someone help me with this errors? Why it happened? How can i solve it? It is a copy paste of existing built-in solution, but in my case it does not work, it asks me additional functions, i do not understand why.

NiagaraDataInterfaceTest.cpp (2.6 KB)
NiagaraDataInterfaceTest.h (1.6 KB)

In case anyone has this issue - make sure that yout build.cs has all the necessary dependencies! You can find the template build.cs file in the same example folder where the DataInterfaceMousePosition example is.
