Empty Build Tables When Connecting to Azure Devops 2019 via OData Feed

[knogas]

We are using Azure Devops 2019 on-premises.  I am trying to pull in Build data into PowerBI via OData as described here:

Here are a couple more examples:

When I connect to our server, I see the various tables but anything build related is empty:

If I execute either of the following through Microsoft Edge, I see that everything should be available:

https://tfsvr2.<org>/tfs/DefaultCollection/<Name>/_odata/v3.0-preview/

https://tfsvr2.<org>/tfs/DefaultCollection/<Name>/_odata/v3.0-preview/$metadata

I know that at some point, I think December 2019, Microsoft changed the Entity Property names in v3.0-preview and is currently on v4.0-preview.  However, since we're on premises, haven't updated anything, and the schema seems correct, I'm at a loss as to why Builds (and releated tables such as BuildPipelines) are empty.

Any suggestions are welcome.  Thanks.
