I am using the canonical HTTP.WebSockets example but getting an iterator error on ws.
```julia
using HTTP.WebSockets
WebSockets.listen(host, convert(UInt16, port)) do ws
for message in ws
@show message
#send(ws, msg)
end
end
```
```julia

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 How do I sync the Manifest and remove the outdated dep of WebSockets?
```julia
(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 To see why use `status --outdated`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 status --outdated HTTP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 ( remove WebSockets
ERROR: The following package names could not be resolved:
* WebSockets (104b5d7c-a370-577a-8038-80a2059c5097 in manifest but not in project)
(Tibra.jl) pkg> remove Mux
ERROR: The following package names could not be resolved:
* Mux (a975b10e-0019-58db-a62f-e48ff68538c9 in manifest but not in project)

I had to remove Blink.jl as apparently its using outdated libraries.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