I still get this error when using Dendron in Windows with WSL:

{
  "ctx": "h:run",
  "err": {
    "status": "unknown",
    "msg": "",
    "payload": "{\"msg\":\"no workspace file\",\"stack\":\"Error: no workspace file\\n\\tat Function.workspaceFile (/home/scott/.vscode-server/extensions/dendron.dendron-0.38.0/dist/extension.js:9:76947)\\n\\tat h.execute (/home/scott/.vscode-server/extensions/dendron.dendron-0.38.0/dist/extension.js:736:86934)\\n\\tat h.run (/home/scott/.vscode-server/extensions/dendron.dendron-0.38.0/dist/extension.js:9:103916)\\n\\tat async /home/scott/.vscode-server/extensions/dendron.dendron-0.38.0/dist/extension.js:9:79730\\n\\tat async S._executeContributedCommand (/home/scott/.vscode-server/bin/3c4e3df9e89829dce27b7b5c24508306b151f30d/out/vs/server/remoteExtensionHostProcess.js:86:106762)\"}"
  }
}

There's an issue already logged for it but it's difficult to use when trying to use different settings and being greeted with the same error each time
