Server in streaming mode - never wrote a response

[sairus7]

Run this example SSE code from docs: https://juliaweb.github.io/HTTP.jl/stable/examples/#Server-Sent-Events:

using HTTP, Sockets, JSON

const ROUTER = HTTP.Router()

function getItems(req::HTTP.Request)
    headers = [
        "Access-Control-Allow-Origin" => "*",
        "Access-Control-Allow-Methods" => "GET, OPTIONS"
    ]
    if HTTP.method(req) == "OPTIONS"
        return HTTP.Response(200, headers)
    end
    return HTTP.Response(200, headers, JSON.json(rand(2)))
end

function events(stream::HTTP.Stream)
    HTTP.setheader(stream, "Access-Control-Allow-Origin" => "*")
    HTTP.setheader(stream, "Access-Control-Allow-Methods" => "GET, OPTIONS")
    HTTP.setheader(stream, "Content-Type" => "text/event-stream")

    if HTTP.method(stream.message) == "OPTIONS"
        return nothing
    end

    HTTP.setheader(stream, "Content-Type" => "text/event-stream")
    HTTP.setheader(stream, "Cache-Control" => "no-cache")
    while true
        write(stream, "event: ping\ndata: $(round(Int, time()))\n\n")
        if rand(Bool)
            write(stream, "data: $(rand())\n\n")
        end
        sleep(1)
    end
    return nothing
end

HTTP.register!(ROUTER, "GET", "/api/getItems", HTTP.streamhandler(getItems))
HTTP.register!(ROUTER, "/api/events", events)

server = HTTP.serve!(ROUTER, "127.0.0.1", 8080; stream=true)

# Julia usage
resp = HTTP.get("http://localhost:8080/api/getItems") # <-- if run from chrome browser, got error together with response

If I paste http://localhost:8080/api/getItems into chrome browser, I get the responce, but there is also an error message in Julia console:

┌ Error: handle_connection handler error.

Is that expexted behaviour? I've encountered this every time when I have streaming mode with HTTP.streamhandler middleware. Without it the message disappears.
