/model/parse api call missing?

Getting Started with Rasa Tutorials, Resources & Videos
1

I’m following the webkit-voice-demo project by @koaning here - RasaHQ/webkit-voice-demo: This is a project that shows how to integrate webkit voice with Rasa. (github.com)

I’m stuck on the API call to my rasa server. It’s making a call to http://localhost:5005/model/parse and my server is returning a 404.

If I hit my server straight with no path (http://localhost:5005), I get the hello message so I know it is indeed running -

Hello from Rasa: 2.6.2

Any ideas? It looks like the /model/parse endpoint is still in the docs.

Am I missing something?

That’s strange. Could you share the logs and the httpie/curl request that you’re making? I’m wondering if the issue is that you’re making a GET request instead of a POST one.

Sure thing. Here’s everything I see and tried -

Here’s the browser console logs -

Listening...
(index):34 This is a test.
(index):35 Confidence: 0
(index):44 POST http://localhost:8000/api/ 500 (Internal Server Error)
recognition.onresult @ (index):44
VM7:1 Uncaught (in promise) SyntaxError: Unexpected token I in JSON at position 0

The uvicorn console spits out this -

uvicorn app:app --reload --port 8000

I changed the api call line to this -

    url = "http://localhost:5005/model/parse"
    results = rq.post(url, json=body)
    print(results.text)

And as you can see I get a 404 error -

To make sure it was finding the server, I changed the url to /webhooks/rest/webhook to see if I get a different error, and it returns no errors so I know it’s hitting my server.

Strange, right?

I ran a typical rasa train, do I need to do just a rasa train nlu or something maybe?

Try run

rasa run --enable-api

Yep, I already am, I can interact with my rasa server with my web chat component so I know it’s running the api.

This is the complete command I’m running FWIW -

rasa run -m models --enable-api --log-file out.log --cors "*" --endpoints endpoints-local.yml --debug

I figured it out - meaning it’s working now.

I stopped my rasa server, and hit refresh on my browser with http://localhost:5005 and I STILL got the Hello message, which clearly shouldn’t have happened.

I apparently already had a rasa server running somewhere else, which occasionally happens some times and since I’m on Wonderful Windows, I have to go to Task Manager and kill all the python 3.7 processes. Once I did that, I spun up the Rasa server again, ran uvicorn and it works now.

Couple strange things about that -

1 - I didn’t get a port conflict message when I fired up the 2nd rasa server

2 - if 2 were running you’d think one of them could serve up the api call

All is well now though.
