BlazorLibrary not working with Codespaces

[dajma00]

I have a project using BlazorLibrary. It works fine on local machine and deployment machine. However, with Github Codespaces, the app crashes with this message:

Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[111]
      Unhandled exception in circuit '0J29eWFlzxc60QQHfWZlWhEWkIfDTW_o4L40QSZTHDY'.

Any ideas why? Looks like BlazorLibrary trying to get some data but failing.

I think the https:///_content/BlazorSchool.Components.Web/Themes/Default/default.min.json is not accessible

hmm.... why the issue on Codespaces only?

I don't know yet. But https:///_content/BlazorSchool.Components.Web/Themes/Default/default.min.json is accessible?

Not sure, but if that was the case, why would it work on my development machine as well as live deployment machine?
