Azure DevOps GVFS Error

Hello VFS Team,

I have configured central Proxy Server for Azure DevOps Server on-premises to consume as GVFS proxy by adding the Repository using below command:
TFSConfig Proxy /add /Collection:https://xxxxxxxxxxxxxxxxxxxxxxxxx/tfs/xxxxxxxxxxx /inputs:GvfsProjectName=Proj1;GvfsRepositoryName=Repo1

And tried to clone from client using GVFS command like below example

gvfs clone https://AzureDevOpsServer/_git/Repo1 --cache-server-url=https://xxxxxxxxxxxxxxxxxxxxxxxxx/repoid1
replacing the VSTS clone url, the cache server address, and the repository id in the cache-server-url as appropriate.

But I am getting following error:

NetworkError {"Area":"GitObjects","Exception":"GVFS.Common.Http.GitObjectsHttpException: Server returned error code 400 (BadRequest). Your PAT may be expired and we are asking for a new one. Original error message from server: A valid Basic Authorization header is required.","Operation":"DownloadAndSaveObjects","WillRetry":false,"ErrorMessage":"GVFS.Common.Http.GitObjectsHttpException: Server returned error code 400 (BadRequest). Your PAT may be expired and we are asking for a new one. Original error message from server: A valid Basic Authorization header is required."}

GVFSClone (Stop) {"DurationMs":8131}

Curious to learn if i am missing any configuration

Start by reviewing and reproducing the TFSConfig Proxy /add configuration and the gvfs clone command with --cache-server-url. Trace the reported 400 BadRequest and missing Basic Authorization header through the clone's GitObjects request; done means the configured proxy can complete the clone without the authorization error.
