研究方向

Reproduce the failure with the provided Repro.Single and Repro.Array manifest script, then trace the TryConvertFromHashtableForPsd1 path named in the error. Add a regression test for a single-hashtable RequiredModules value and verify Find-PSResource, Save-PSResource, and Install-PSResource handle it like the array form.

Steps to reproduce

I think the following is correct, Claude Code suggested I raise it!

Steps to reproduce

RequiredModules = @{ ModuleName = 'X'; ModuleVersion = '1.0.0' } (a single hashtable, not wrapped in @()) is a valid module manifest. Import-Module, Test-ModuleManifest and the PowerShell Gallery all accept it, and dbatools uses it (dbatools 2.9.0 requires dbatools.library this way). But PSResourceGet cannot find, save or install such a package from a local (file-share) repository, even with -SkipDependencyCheck. The same manifest with RequiredModules = @(@{ ... }) works.

$Work = Join-Path ([IO.Path]::GetTempPath()) ([guid]::NewGuid())
New-Item -ItemType Directory -Path "$Work\pkg", "$Work\out" -Force | Out-Null
foreach ($Case in @{ Name = 'Repro.Single'; Requires = "@{ ModuleName = 'Repro.Lib'; ModuleVersion = '1.0.0' }" },
                  @{ Name = 'Repro.Array';  Requires = "@(@{ ModuleName = 'Repro.Lib'; ModuleVersion = '1.0.0' })" }) {
    $Src = New-Item -ItemType Directory -Path "$Work\src\$($Case.Name)" -Force
    Set-Content "$Src\$($Case.Name).psm1" ''
    Set-Content "$Src\$($Case.Name).psd1" "@{ RootModule = '$($Case.Name).psm1'; ModuleVersion = '1.0.0'; GUID = '$([guid]::NewGuid())'; Author = 'T'; Description = 'T'; RequiredModules = $($Case.Requires) }"
    Compress-PSResource -Path $Src -DestinationPath "$Work\pkg" -SkipModuleManifestValidate
}
Register-PSResourceRepository -Name Repro -Uri "$Work\pkg" -Trusted
Save-PSResource -Name Repro.Array  -Version 1.0.0 -Repository Repro -Path "$Work\out" -TrustRepository -SkipDependencyCheck   # works
Save-PSResource -Name Repro.Single -Version 1.0.0 -Repository Repro -Path "$Work\out" -TrustRepository -SkipDependencyCheck   # fails
Unregister-PSResourceRepository -Name Repro

The same happens with the real package: Save-PSResource -Name dbatools -AsNupkg from PSGallery, register that folder as a repository, then Find-PSResource -Name dbatools -Repository <it>.

Find-PSResource and Install-PSResource fail the same way. A package that depends on dbatools then fails with Dependency package with name 'dbatools' could not be found in repository.

Expected behavior
`Repro.Single` is found and saved, as `Repro.Array` is, with `Repro.Lib` as its dependency.
Actual behavior
Save-PSResource: TryConvertFromHashtableForPsd1: Could not find expected information from module manifest file hashtable with error: Object reference not set to an instance of an object.
