Error C4430 & C2143 implementing GAS

Helloooooooo FOLKS!!!

I’m having really bad time trying to implement GAS in a project.
I’m a newbie about Unreal/C++, got experience on Unity/C#.

I found a guide about GAS

When he builds at 20.30 I got an error on AttributeSet.h

BUT THAT IS STUFF GIVEN BY THE PLUGIN I DIDN’T TOUCH IT…at least I’m almost sure I didn’t touch it.

I downloaded that guide repository a few weeks ago and looked at how he handled all of it in his project.
Now it is giving me the same error in his project when I try to open it from the solution…

Any ideas? If you need more infos just let me know what!!

That’s strange, already added the modules to your project build.cs?

If not, try adding this to PublicDependencyModuleNames in your project build.cs:

"GameplayAbilities",
"GameplayTags",
"GameplayTasks",

I already did it!
