Additional context

We observe the issue is with spring extension 1.28.5 version (latest as of today 10/15)
To unblock this issue, we have installed the 1.28.4 version.

az extension add --upgrade --yes --name spring --> this command installs 1.28.5 version of spring extension which is causing issue hence we stated using
az extension add --yes --name spring --version 1.28.4 --> to install and use spring extension (previous version 1.28.4)
