Steps to reproduce

Find/Save/Install-PSResourceGet fails with some Nuget v3 repositories, ex. https://preview.pwsh.gallery, using latest preview.

This is likely caused by the mandatory checks for @id in dependencyGroup and dependencies introduced in #1778.

PSResourceGet/src/code/PSResourceInfo.cs

Lines 728 to 730 in 06aec34

    
           JsonElement dependencyGroup in dependencyGroupsElement.EnumerateArray().Where( 
        
               x => !string.IsNullOrWhiteSpace(x.GetProperty("@id").GetString()) 
        
           )

PSResourceGet/src/code/PSResourceInfo.cs

Lines 737 to 740 in 06aec34

    
           foreach ( 
        
               JsonElement dependency in dependenciesElement.EnumerateArray().Where( 
        
                   x => !string.IsNullOrWhiteSpace(x.GetProperty("@id").GetString()) 
        
               )

@id is not listed as required in docs for dependencyGroup and dependencies, so we should probably not rely on them.

Expected behavior

Find-PSResource, Save-PSResource, Install-PSResource should work with all Nuget v3 repositories

Actual behavior

PS > Register-PSResourceRepository -Name pwshgallery -Uri "https://preview.pwsh.gallery/index.json" -ApiVersion V3
PS > Find-PSResource -Repository pwshgallery -Name az

Interesting, pwsh.gallery and preview.pwsh.gallery gives different results.

pwsh.gallery: https://pwsh.gallery/registration/az/index.json
preview.pwsh.gallery: https://preview.pwsh.gallery/az/page/recent.json

Seems to me that pwsh.gallery uses Sleet, but not preview.pwsh.gallery? Thats what the index tells us at least.

pwsh.gallery: https://pwsh.gallery/index.json
preview.pwsh.gallery: https://preview.pwsh.gallery/index.json

I tested Find-PSResource -Repository 'pwsh.gallery' -Name 'Az', it worked. But Find-PSResource -Repository 'preview.pwsh.gallery' -Name 'Az' did not.

So it works with Sleet?

We should probably conform to the spec, not checking for something that is not mandatory. Even though Sleet outputs @id too.

I believe changing from getting @id to id should fix it.

You're right. I mixed up preview and prod pwsh.gallery at one point. 🤦‍♂️

Preview is probably not Sleet.
