Package error on Mac for ios

I downloaded a plugin named VaRest from market place.
In my project ,I enabled this plugin.When I try to pakage it,it shows some errors as following.
mono: UnrealBuildTool Exception: ERROR: Not expecting project /Users/Kevin/Documents/Unreal Projects/UE402/Intermediate/ProjectFilesIOS/UE4.xcodeproj to already have a target rules of with configuration name Game (UE4GameTarget) while trying to add: UE4Target

How can I fix it?

I don’t have an answer for you, but I have been packaging for iOS using VaRest without problems for a while now. You should reach out to the developer through the forum. The developers name on the forums is ufna

I hope you find your answer.

I created a C++ class, and when packaging iOS, got this error too,
ERROR: Not expecting project /Users/86185/UE4/Builds/DESKTOP-N5JLND9/D/EpicWork/MyProject5/Intermediate/ProjectFilesIOS/MyProject5.xcodeproj to already have a target rules of with configuration name Game (MyProject5Target) while trying to add: MyProject5Target
so ,what should I do? thanks a lot!
