Make sure you are using the right SIF version, which in this case is 2.0.0.

The following command will show you your current version:

Get-Command -Module SitecoreInstallFramework | Select-Object -Property name, version

If you are still using SIF 1.2.1 you just need to upgrade it using the following commands:

To list all installed SIF versions

Get-InstalledModule -Name SitecoreInstallFramework -AllVersions

If you already have SIF 2.0.0 installed, you just need to set it as the current used version

Remove-Module -Name SitecoreInstallFramework
Import-Module -Name SitecoreInstallFramework -RequiredVersion 2.0.0

If you don't have SIF 2.0.0, then you must install it

Install-Module -Name SitecoreInstallFramework -RequiredVersion 2.0.0
