FamilyManager.AddParameter expects types not consistent with documentation

I’m trying to change a script that configures a family to operate from a project document instead of a family document. Also trying to learn the family document and FamilyManager interactions. Specific context: building a key plan family with area visibility parameters

part of this is adding some family parameters. when i call AddParameter i’m trying to use the ForgeTypeIds as indicated in the 2022 API docs, but get this error

TypeError: expected BuiltInParameterGroup, got ForgeTypeId

Am i misreading something here?

Can you run a quick test to see if SpecTypeId.Boolean is in fact a ForgeTypeId? It’s been a bit but I recall one of these required an additional constructor somewhere… but I don’t know exactly where and am not at the laptop this evening.
