Sinatra - downstream app not set

I'm getting this strange error: downstream app not set

However my app is responding and working well.

I've checked - and I've not found any requests to undefined routes. (Maybe there is some tools to debug that)

Checked Google too.

Please help - how to remove this error.

    get "/favicon.ico" do
end

    Solved the problem
