Actual behavior

Does not give version range for all but `Az.Accounts`.

Error details

Environment data

PSResourceGet v1.1.1

Visuals

No response

[o-l-a-v]

Just noticed MAR latest version of Az is 13.5.0, while PSGallery has 14.0.0. This did not affect the results though, tried the same with specifying version.

I don't know if this is a problem in the Azure powershell publishing to MAR process, a MAR problem, or a PSResourceGet problem.

[o-l-a-v]

I did some digging: Metadata in MAR contains all the version numbers.

    Invoke-RestMethod -Method 'Get' -Uri 'https://mcr.microsoft.com/v2/psresource/az/manifests/14.4.0' -Headers @{

So PSResourceGet messes up the parsing of this JSON. I could reproduce this in PowerShell, and also got it working by ConvertFrom-Json -AsHashtable.

# MAR API
## Get metadata as JSON
$MetadataJson = [string](
    (
        Invoke-RestMethod -Method 'Get' -Uri 'https://mcr.microsoft.com/v2/psresource/az/manifests/14.4.0' -Headers @{
            'Accept' = [string] 'application/vnd.oci.image.manifest.v1+json'
        }
    ).'layers'.'annotations'.'metadata'
)

## Convert from JSON to PSCustomObject - Only version for the first module in the list is returned
($MetadataJson | ConvertFrom-Json).'ModuleList'

## Convert from JSON to hashtable - Version for all modules are returned
($MetadataJson | ConvertFrom-Json -AsHashtable).'ModuleList'

I'll see if I can see something in the code for MAR.

[o-l-a-v]

Looks like it's ParseContainerRegistryDependencies in PSResourceInfo.cs that fails to get version info.
