[V7] ReadIdentities doens't work as intended

Using github.com/microsoft/azure-devops-go-api/azuredevops/v7/identity / ReadIdentities(context.Context, ReadIdentitiesArgs) (*[]Identity, error) should target https://vssps.dev.azure.com/fabrikam/_apis/identities.

Context

"github.com/microsoft/azure-devops-go-api/azuredevops/v7/identity"

test := "aad.MDA0NzBlMzQtZGE2MS03YTY5LWJkOTYtNDg3YTg0OWVjNTU4"
legacyIdentities, err := identityClient.ReadIdentities(ctx, identity.ReadIdentitiesArgs{
  SubjectDescriptors: &test,
  QueryMembership:    &identity.QueryMembershipValues.None,
})

Waited behavior:

Using subjectDescriptors with a VSId and queryMembership=None should works in 7.1-preview.1

URI should be like: https://vssps.dev.azure.com/fabrikam/_apis/identities?subjectDescriptors=aad.MDA0NzBlMzQtZGE2MS03YTY5LWJkOTYtNDg3YTg0OWVjNTU4&queryMembership=None&api-version=7.1-preview.1 according to the doc. (and working in with curl/postman)

Current behavior:

Using subjectDescriptors with a VSId and queryMembership=None in 7.1-preview.1 return:

Invalid argument value.\r\nParameter name: The identity (no guid supplied) is not recognized.

Is it using another endpoint?

Start at the identity.ReadIdentities entry point and reproduce the supplied call with the subject descriptor and queryMembership=None. Compare the request URI it produces with the documented Azure DevOps 7.1-preview.1 endpoint; done means the call targets the expected URI and returns identities without the reported invalid-argument error.
