Problem getting HTTP.Websocket Server example working

General Usage
1

I am using the canonical HTTP.WebSockets example but getting an iterator error on ws.

    using HTTP.WebSockets

    WebSockets.listen(host, convert(UInt16, port)) do ws
        for message in ws
            @show message
            #send(ws, msg)
        end
    end

Can you double check what version you’re on? It seems like maybe you’re stuck on an old one before this was defined?

Yea that must be it. How do I sync the Manifest and remove the outdated dep of WebSockets?


(Tibra.jl) pkg> status HTTP
Status `~/src/tibra/Tibra.jl/Project.toml`
⌅ [cd3eb016] HTTP v0.9.17
Info Packages marked with ⌅ have new versions available but compatibility constraints restrict them from upgrading. To see why use `status --outdated`

(Tibra.jl) pkg> status --outdated HTTP
Status `~/src/tibra/Tibra.jl/Project.toml`
⌅ [cd3eb016] HTTP v0.9.17 (<v1.7.4): Mux, WebSockets

(Tibra.jl) pkg> remove WebSockets
ERROR: The following package names could not be resolved:

I had to remove Blink.jl as apparently its using outdated libraries.

Mux has a newer version that supports HTTP 1.0. Ah, I see you just replied about Blink.jl.
