PSResourceGet v1.1.1 not working with Nuget.Server v3.4.2

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

I have compiled and deployed Nuget.Server per Microsoft documentation. With the latest PSResourceGet I have registered a PSResourceRepository with the following parameters.

Register-PSResourceRepository -Name psrepo -Uri https://psrepo/nuget -Trusted -ApiVersion NugetServer

Calling Find-PSResource fails with the following:

PS> Find-PSResource -Name ExistingModule -Repository psrepo
DEBUG: In FindPSResource::ProcessResourceNameParameterSet()
DEBUG: Filtering package name(s) on wildcards
DEBUG: In FindHelper::FindByResourceName()
DEBUG: Parameters passed in >>> Name: 'E7ADSitePlan'; ResourceType: 'None'; VersionRange: ''; NuGetVersion: ''; VersionType: 'NoVersion'; Version: ''; Prerelease: 'False'; Tag: ''; Repository: 'psrepo'; IncludeDependencies 'False'

Find-PSResource: TryConvertFromXml: Cannot parse PSResourceInfo from XmlNode with error: Object reference not set to an instance of an object.

Note that calling the API endpoint directly does return a response.

Additionally of note is that the search function appears to erroneously include the Module name in the version query parameter if version is specified...

PS> Find-PSResource -Name ExampleModule -Version '1.1.1.1' -Repository psrepo
DEBUG: In FindPSResource::ProcessResourceNameParameterSet()

DEBUG: Searching through repository 'psrepo'
DEBUG: In FindHelper::SearchByNames()

Find-PSResource: Package does not exist on the server

In the request url you can see NormalizedVersion eq "ExampleModule" is present in the url.

Expected behavior

Searches succeed

Actual behavior

I think PSResourceGet uses dumb logic to determine API type, and it tries to incorrectly parse v2 nuget as nuget.
Try changing NuGetODataConfig.cs: NuGetV2WebApiEnabler.UseNuGetV2WebApiFeed param "nuget" to "nuget/v2", update your repo URL and try running Find-PSResource again.
Find-Module works correctly without URL change, so it is a bug with PSResourceGet.
