Hello, I tried to open it in a browser, with address http://localhost:5005, it returned ‘hello from Rasa 1.2.5’ but http://localhost:5005/favicon.ico, it returned the error above. But if I don’t open the browser, and test in another terminal, for example I sent:

curl -XPOST localhost:5005/webhooks/rest/webhook -d '{"sender":"Me","message":"how are you?"}'

It replied me [{"recipient_id":"Me","text":"I'm doing very well. Thanks!"}]

I have this as well

Running Windows 10, fwiw.

When I initially execute rasa run there are no errors in the console.

Simply hitting the url : http://localhost:5005/ correctly show this in the browser: Hello from Rasa: 1.2.5

However hitting that url in the browser causes the following to display in the console:

Exception occurred while handling uri: 'http://localhost:5005/favicon.ico'

sanic.exceptions.NotFound: Requested URL /favicon.ico not found

I don’t think it’s a big deal, it’s simply not finding the favicon file when the Sanic server spins up.

Just for fun I dropped a random one in the root of the project, restarted rasa but that didn’t seem to help, which makes sense, the Sanic server DocRoot is probably elsewhere.

edit: Just to verify this is the result of a 404, the ngrok console displays this:
