ERROR: Cannot validate argument on parameter 'Uri'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.
The install of tmp5dac.tmp was NOT successful.
Error while running 'C:\ProgramData\chocolatey\lib\tmp5DAC.tmp\tools\ChocolateyInstall.ps1'.

I read the WindowsTemplateStudio.ps1 script ,
at line 14
$wtsFileUrl = $wtsResults.versions[0].files | where {$_.assetType -eq "Microsoft.Templates.2017.vsix"};
,but there is no file named Microsoft.Templates.2017.vsix on the
website https://marketplace.visualstudio.com/_apis/public/gallery/extensionquery.
