Empty clues crash the bot

[Columbus240]

Version : v1.8.1 Convention settings: H-Group. tested levels 1, 2, 11 Steps to reproduce or replay link:

• Create a game with empty clues allowed.
• Invite the bot and start the game.
• At any point in the game give the bot an empty clue.
• The bot crashes (the process exits).

Additional information: The bot is unable to figure out the focus of the empty clue and crashes. Part of the log:

file:///…/hanabi-bot/src/conventions/h-group/hanabi-logic.js:65                         
                throw new Error('No focus found!');                                                    

I don't expect a fix, just wanted to inform people about it.

Is there a workaround to reconnect the bot to a game or otherwise to continue playing?

The H-Group doesn't play with empty clues, so there's no conventional interpretation of such a clue. I guess I could just treat it as no interpretation other than eliminating some possibilities, if that's how it's normally played.

The bot can be asked to rejoin a game by sending it /rejoin in a private message, though its level will need to be reset first using /settings. More information on these commands are in the README. However, if the bot crashed due to some game event, then asking it to rejoin will just cause it to crash again.

In general, I would just avoid playing with variants/options that the bot doesn't support (i.e. anything other than the standard options in No Variant, Black, White, Rainbow, Prism, Pink or Brown), since it is prone to crashing or behaving strangely otherwise. I'll add this info to the README as well.
