Need Help to use Rasa Core Server


I am trying to use Rasa in a new personal project. I want to use the CORE HTTP API but the /conversations/{sender}/parse route is not available. It returns a 404.

Has some someone succeeded to make it work? If yes can I have some help?

I trained the NLU part using

python -m rasa_nlu.train --config conf.yml --data --path projects

and then I trained the Story part using

python -m rasa_core.train -d domain.yml -s -o models/current/dialogue --epochs 200

No special error was raised. When I launch the server using

python -m --enable_api -d models/current/dialogue -u models/current/nlu -o out.log --debug

I can’t see the parse route whereas it’s mandatory to start…


Thanks in advance


Hey @ThibautCollette.

I can see that you save your NLU model inside the directory called ‘projects’, which means that after you run the first command your model is saved in ./projects/default/model_xxx . However, when you start the sever (running function), the path you provide for your nlu model is models/current/nlu. I would expect you to get the 'No such file or directory: 'models/current/nlu\\metadata.json'' error here. To fix that you should specificy the correct path for your nlu model which is projects/default/model_xxxxxxxx.

Alternatively, you can change the directory where you save the nlu model after it’s trained. For example, using the following command:

python -m rasa_nlu.train -c conf.yml --data data/ -o models --fixed_model_name nlu --project current --verbose

your nlu model will be saved inside the models/current/nlu dorectory and therefore match the path you originally specified in function.

Hello @Juste, Thank you very much for your reply. I indeed, run again the nlu_train command with what you suggested before being able to launch the server, you’re right. Once I did that I was still facing the issue mentioned that the parse route was not available…

I restarted and did what you do but here is the debug logs from

As you can see there is no /conversations/[sender_id]/parse route…

I am having the same issue. Please help.

as per the Changelog these endpoints are now removed.


  • outdated documentation for removed endpoints in the server ( /parse & /continue )"

Try looking at the latest documentation for the changes.


Thank you very much for your response. I’ve seen this changelog was published today (for version 0.11.2) but documentation latest version is 0.11.1. Maybe it will be available later today. I’ll wait a bit and see.

Thank you

In the meantime, file is available here:

Thank you very much for your help, I’ll check that out tonight :slight_smile:

Yeah sorry about that, the docs are now updated and so is the migration guide:
