Running Rasa in Pycharm debugger

I’m trying to run Rasa (not Action server, but Rasa itself) in PyCharm debugger. I an executing rasa module with “run --enable-api --debug --endpoints endpoints.yml” as parameters.

It runs, but clients cannot connect to it. I have tried both socketio and facebook, and they have the same error:

[2019-08-17 12:27:14 -0700] [2918] [ERROR] Exception occurred while handling uri: 'http://localhost:5005/'
Traceback (most recent call last):
  File "/Users/michael/Documents/projects/rasa2/env/lib/python3.6/site-packages/sanic/", line 893, in handle_request
    handler, args, kwargs, uri = self.router.get(request)
  File "/Users/michael/Documents/projects/rasa2/env/lib/python3.6/site-packages/sanic/", line 407, in get
    return self._get(request.path, request.method, "")
  File "/Users/michael/Documents/projects/rasa2/env/lib/python3.6/site-packages/sanic/", line 469, in _get
    raise NotFound("Requested URL {} not found".format(url))
sanic.exceptions.NotFound: Requested URL / not found

Has anyone has success with this?

Note that it works fine when running in terminal.

Hi @mmm3bbb, could you post the contents of your endpoints.yml file, as well as the full output of the run command when you run it with --debug? Thanks.

Hi @fede. OK, it was a working directory problem. Your hint to look at --debug helped me figure that out. Thx. However, I do get this message with an error at the end. It still runs though.

Glad you were able to solve the directory problem. So now it runs, but you can’t actually use it, correct?

I found that the biggest ‘gotcha’ was setting the interpreter to use. Assuming you’ve created an environment to run rasa in and you’ve downloaded the code, when you open the rasa project you must set the Python interpreter in settings to something as below:

As you can see I used conda and setup a rasa environment. All the dependencies needed to run rasa have been loaded into it. this was confirmed by being able to rasa run from the installed directory.

Here is a screenshot of Pycharm configuration to debug.

let me know if you face problem configuring it.

Hi I am pretty new to Rasa and Pycharm. Can you please help me learn how to set the debugger environments in Pycharm.

I have added a screenshot in the above link. Could you please follow it and let me know where you are stuck?

thank you Lohith, Followed the same. But still no success, any way we can have a PM. I can share my screen, for you to have a quick look, if you can help me. Will be interested to learn from you.

I have actually written an article around running/debugging Rasa in PyCharm - here is the link in case this helps anyone looking: Running and Debugging Rasa Applications in an IDE | by Daniel Cahall | Jul, 2021 | Medium

This is how the rasa action server is configured
