Is WebResourceService broken?

[CGNonofr]

When fetching for instance https://open-vsx.org/vscode/unpkg/vscodevim/vim/1.29.0/extension/out, the endpoint returns the list of file in that directory which is expected

When trying to fetch one of those files: https://openvsxorg.blob.core.windows.net/resources/vscodevim/vim/1.29.0/extension/out/extensionBase.js, the file content is returned, which is expected

But when trying to fetch another file: https://open-vsx.org/vscode/unpkg/vscodevim/vim/1.29.0/extension/out/extensionWeb.js, an empty array is returned instead of the file content, feeling like the file is considered somehow as a directory
