Error "Invalid Scheme" when trying to preview a rst file.

[cosmarc]

When I try to preview a .rst file in VS code I get the following error:

The weird thing is that I have the v0.16.4 installed while the extension is still loading v0.16.1. Is it bundled directly in the extension?

pip show esbonio

Version: 0.16.4
Summary: A Language Server for Sphinx projects.

Please find below the output of the extension.

Have you opened VSCode without a workspace? i.e. There's no folder open in the explorer view
If so, opening your project's folder in VSCode should be enough to work around the issue 🤞

The weird thing is that I have the v0.16.4 installed while the extension is still loading v0.16.1. Is it bundled directly in the extension?

Yes, in the pre-release version of the extension (v0.90+) the language server is now bundled with the VSCode extension itself. Unfortunately however, the version number reported is misleading, it should say it's loading v1.0.0b0 of the server as it is nothing like the 0.16.4 version you have installed separately.

If you would rather use the 0.16.x version of the server you will need to use the non pre-release version of the VSCode extension (v0.11.0)
