Alexa error

in kubuntu18.04 I install:
sudo snap install alexa --beta

but when execute: alexa.alexa-run
I have:

xcb_connection_has_error() returned true
Failed to create secure directory (/run/user/0/snap.alexa/pulse): No such file or directory
Traceback (most recent call last):
File “/snap/alexa/2/bin/”, line 20, in
File “/snap/alexa/2/bin/”, line 10, in main
File “/snap/alexa/2/bin/”, line 29, in init
+ str(pa.strerror(error), ‘ascii’))
Exception: Could not create pulse audio output stream: No such device or address

what I missing?

thank you

Looking at the error messages it looks like a file for pulse audio is missing which is needed. The snap was last updated April 2017 by the developer. So I would recommend you trying to contact the developer and see if they update the snap and fix the error.
