Help listing repositories

I am trying to get a list of all repositories under a project.

I was able to get the desired project however I am stuck on the build.ListRepositories call

var name string = *projectRef.Name
var ProviderType string = "Git"

buildClient, err := build.NewClient(ctx, connection)
if err != nil {
    log.Fatal(err)
}

response, err := buildClient.ListRepositories(ctx, build.ListRepositoriesArgs{Project: projectRef.Name, ProviderName: &ProviderType })

Using ProviderType "Git" yields
Value cannot be null. Parameter name: serviceEndpointId

I browsed to https://dev.azure.com/{org}/{project}/_apis/serviceendpoint/endpoints?api-version=7.0

And found there are no endpoints

I browsed to https://dev.azure.com/{org}/{project}/_apis/sourceproviders?api-version=7.0
and found the following options:

• TfsVersionControl
• GitHubEnterprise
• Svn
• GitHub
• BitBucket
• Git
• TFSGit

When trying TfsVersionControl or TfsGit the ListRepositories() call never resolves.
We are using Microsoft's hosted Azure Devops (dev.azure.com) for hosting.

I tried curling the repositories endpoint using my PAT base64 encoded as a bearer token.

curl -L -X GET \ -H "Authorization $PAT" \ "https://dev.azure.com/{org}/{project}/_apis/git/repositories?api-version=7.0"

When running this I get an error

Microsoft Internet Explorer's Enhanced Security Configuration is currently enabled on your environment.

is it possible I am correctly using buildClient.ListRepositories() and it's not catching this error?
Do we have to create a service endpoint in order to list repositories?

Start with build.ListRepositories and compare its request with the listed Azure DevOps repositories and sourceproviders endpoints. Reproduce the serviceEndpointId error and the hanging provider calls using the issue's examples. Done means the required endpoint or API behavior is established and the failure is documented or corrected.
