Error on BP_Weapon_Component while packagingFirst Person Template

Hello!

I’ve developed a really simple game to test the First Person Template, but when I try packaging the project a get some errors. I was able to track the BP causing the problems and it’s a default BP from the template, that I have’nt altered. When I try to compile it, I get the following error messages

EnhancedInputActionEvent references invalid 'null' action for  EnhancedInputAction None
The property associated with  Has Rifle  could not be found in '/Game/FirstPerson/Blueprints/BP_FirstPersonCharacter.BP_FirstPersonCharacter_C'
The property associated with  First Person Mesh  could not be found in '/Game/FirstPerson/Blueprints/BP_FirstPersonCharacter.BP_FirstPersonCharacter_C'

I searched a bit around the forums, but I was’nt able to find a solution, probably because
I’m really new in Unreal and game dev in general

Here’s a print screen of one of the parts that does’nt compile
