Web app .NET8 for Sidebar - menu keeps spinning - SidebarDataProvider doesn't seem to complete

[skippyV]

Just tried to follow the instructions on https://docs.blazorbootstrap.com/getting-started/blazor-webapp-server-global-net-8.
The code in MainLayout.razor has one different statement than that listed in https://demos.blazorbootstrap.com/sidebar.
But that doesn't seem to be my problem.

The sidebar menu never appears and the 3 dots of the sidebar just keep cycling.

Attaching the project.
BlazorAppSidebarColors.zip

Please advise

After diffing my project (created with VS .NET8 web app template and with Interactive render mode: Server and Interactivity location: Per page/component) with the BlazorBootstrap NET8.BlazorWebAppRenderModeServerGlobal project, the App.razor had 2 significant differences.
@rendermode="@InteractiveServer"
was included as a property for head->HeadOutlet element and the body->Routes element in the BlazorBootstrap version.

After adding @rendermode="@InteractiveServer" to body->Routes resolved my issue.
