On rstudio server, the viewer pane url is like /p/f425e0d9/
But the render job cannot find the html to serve
```
Watching files for changes
quarto.html
GET: / (404: Not Found)
```
Html exists and can be opened manually. 

ps: I am running this with jupyterhub + server proxy.  Shiny app and rmarkdown with knitr all works fine. Only quarto have this issue.
