Build Error

[Scaramanga]

I installed mod tools and used the "feline" template. Once I build though:

Error 1 The "GenerateModInfo" task failed unexpectedly.
System.UriFormatException: Invalid URI: The format of the URI could not be determined.
at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
at System.Uri..ctor(String uriString)
at Firaxis.VisualStudio.Tasks.Civ6.GenerateModInfo.Execute()
at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute()
at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__20.MoveNext()

I assume it's talking about this section of the Civ6.targets file:

<GenerateModInfo
ID="$(Guid)"
Version="$(ModVersion)"
Name="$(Name)"
Teaser="$(Teaser)"
Description="$(Description)"
Authors="$(Authors)"
SpecialThanks="$(SpecialThanks)"
Homepage="$(Homepage)"
AffectsSavedGames ="$(AffectsSavedGames)"
SupportsSinglePlayer="$(SupportsSinglePlayer)"
SupportsMultiplayer="$(SupportsMultiplayer)"
SupportsHotSeat="$(SupportsHotSeat)"
CustomProperties ="$(ModProperties)"
ActionCriteriaData ="$(ActionCriteriaData)"
LocalizedTextData ="$(LocalizedTextData)"
FrontEndActionData ="$(FrontEndActionData)"
InGameActionData ="$(InGameActionData)"
AssociationData ="$(AssociationData)"
Files="@(ModFiles)"
TargetPath="$(ModInfoPath)"/>

But I have no idea what the invalid URI is.
