Custom Emoji Filesystem settings caused the program failed to start

[ray24777]

Description:

I edited Custom Emoji Filesystem settings and restarted the server. However, it seems that the server have no permissions in this path and fail to start. I cannot remove the previous edit since I cannot login to the control panel. Using the command journalctl -fu snap.rocketchat-server.rocketchat-server shows that Aug 10 11:24:02 VM-12-11-ubuntu rocketchat-server.rocketchat-server[1483567]: Error: EACCES: permission denied, mkdir '/home/ubuntu/emoji'

Steps to reproduce:

1. Go to Administration > Settings > Custom Emoji Filesystem.
2. Choose filesystem and input /home/ubuntu/emoji (Any path that rocket.chat-server have no permission).
3. Restart the program.

Expected behavior:

There should be some kind of ways to remove such error edits.

Actual behavior:

The server failed to restart.

Server Setup Information:

I had the same problem, snap couldn't use file addresses outside of snap, so I ended up re-deploying through rocketchatctl :(

Is it possible to edit the config from mongo console directly?
