Hi Kaniz.
Yes, I have an API that uses that method of the SDK to retrieve the status of the clusters in the workspace and show it in a web site. If we activate Model Serving, a cluster is created that makes the SDK (and therefore, our API) fail.
We are going to try the preview of Serverless Model Serving, so we will probably not have this type of clusters in the future but, right now, itยดs failing. We have tried with the 2.0.0-RC version of the SDK, in case it was fixed, but it has the same issue.
