[weiczhu]

Rasa version:
1.0.1
Python version:
3.7
Operating system (windows, osx, ...):
Ubuntu
Issue:
Starting Rasa X in local mode... 🚀
[2019-05-27 17:09:47 +0900] [16856] [ERROR] Unable to start server

During handling of the above exception, another exception occurred:

Is there any way to configure the RASA X port number?
The following
rasa x --port PORT
does not work

Content of configuration file (config.yml):

Content of domain file (domain.yml) (if used & relevant):

The thing is that we actually need two ports, one to run rasa-x (e.g. delivering the UI) and another one to run a normal rasa server. --port only changes the port of the rasa server, there is no argument to change the rasa-x port.

I think we should add a new argument to specify the rasa-x port and throw an error explaining the two ports thingy if binding to the address fails.

Feature will be included in the next minor release.

i give
rasa x --debug --enable-api --cors "*" --port 5007 --rasa-x-port 5008

and get
Starting Rasa Core server on http://localhost:5007
Error: Cannot connect to host localhost:5008 ssl:None [Connect call failed ('127.0.0.1', 5008)]
(http://localhost:5008/api/health is not responding)

The server is running at http://localhost:5002/login?

can you please share what i am breaking while changing the port from 5002?

rasa-x : 0.19.0

[tabergma]

I guess, you need to use at least rasa-x version 0.19.1. Can you use that version and try again?

[cyrilthank]

indeed you are right

but now i am getting the below output on http://localhost:5008/api/version
after i installed from https://pypi.rasa.com/simple/rasa-x/

{
"rasa": {
"production": "1.1.4",
"worker": "1.1.4"
},
"rasa-x": "UNDEFINED - this package is not installed"
}
