Unable to set the language to Chinese

[HertZPY]

Enter the 'tutor local quickstart' command in the terminal and 'zh-cn' in the default language of the platform. The following error occurs:

[regisb]

This is not due to the language change. The problem is that the container is not running.

[HertZPY]

@regisb However, changing the language to en does not cause this problem

@HertZPY does the error still occur? Can you please identify what is this container? You can see this by running:

docker ps | grep 602cf # or whatever its id is

Then, please paste here the logs of this container:

docker logs putthecontaineridhere

I managed to reproduce the issue. This is caused by the fact that the discovery service does not support Chinese, as you can see with:

$ tutor local logs --tail=100 discovery

I'll work on a fix.
