Sonar Scanner can't find local app data folder - docker

Question

I'm trying to get Sonar Scanner to analyze a project as part of a dockerfile using the mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1809 image, but it's throwing the following exception when attempting to run dotnet-sonarscanner begin
Unhandled exception. System.IO.IOException: Cannot find local application data directory.
I've verified that the folder it's looking for exists on the container with the following powershell command:
RUN pwsh -Command Get-ChildItem $env:LOCALAPPDATA -Directory
Not sure what I'm missing here. Here's a more complete picture of the dockerfile with example data:
