When serving static files, I get the following error.

Exception message: Operation performed on a socket which has not been registered with the dispatcher yet

OS: Windows 11, Nim version: 1.6.0
Source code:

# imports and function definitions ...

var app = newApp(settings = settings) # debug is true
app.use(sessionMiddleware(settings))
app.use(staticFileMiddleware("static"))

app.get("/some_route", render_route1, name = "route1")
app.get("/some_other_route", render_route2, name = "route2")
app.get("/", render_main, name = "main")
app.all("*", render_404)

app.run()

Any idea why ?

[ringabout]

That's strange. Could you try the latest Prologue version (0.5.4) which includes a critical fix?

Anyone ever figured the answer to this? Having the same issue on Win10 with prologue 0.6.4 when I use websockets. If I build for linux and run the app using WSL I have no issue.
