xcb_connection_error() returned true with gTTS library

Question

I'm trying the following simple code with module gTTS, but it isn't working.

from gtts import gTTS
import os
tts = gTTS(text="hello",lang='id')
tts.save("uhuy.mp3")
os.system("mpg123 uhuy.mp3")

When I try to run it I get xcb_connection_has_error() returned true:

What's the problem here?

Answer 1

Looks like X server access issue.

Try adding the user running the program to the xhost DB:

xhost +SI:localuser:the_username_here
