%AppData% folder not correctly replaced in appsettings.json

I have the following appsettings.json:

"Serilog": {
    "Using":  [ "Serilog.Sinks.File" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      { "Name": "File", "Args": { "path": "%APPDATA%\\CompanyName\\ApplicationName.txt", "rollingInterval": "Day", "fileSizeLimitBytes": 26214400, "rollOnFileSizeLimit":  true } }
    ],
    "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
    "Destructure": [
      { "Name": "ToMaximumDepth", "Args": { "maximumDestructuringDepth": 4 } },
      { "Name": "ToMaximumStringLength", "Args": { "maximumStringLength": 100 } },
      { "Name": "ToMaximumCollectionCount", "Args": { "maximumCollectionCount": 10 } }
    ],
    "Properties": {
      "Application": "Name"
    }
  },

and I initialize Serilog reading the resulting configuration. Anyway, the result is not exactly what I would expect (using the AppData system folder). I get instead an %AppData% folder created and containing the logs:

Hi, @fleed , @mishrapw , @nblumhardt . Actually, it should work (just tested), see https://github.com/serilog/serilog-settings-configuration/blob/dev/src/Serilog.Settings.Configuration/Settings/Configuration/StringArgumentValue.cs#L31

what version of the package do you use?

Aha! I’d forgotten about the progress on this, sorry 😃
