Exception stating "cannot send an empty message" when using /chat about bard-discord-bot

[plon]

Done.

I suspect it might be related to the formatting used on text in the chat prompt - notice the "queen - obscene" part.

I was able to get it to fail with "/chat what about this?"

[revblueldd]

Interestingly an asterisk works as a math operator like with "/chat what is 4 * 2?" but does not when you use a pair of them to format the text between them.

[plon]

Can you paste the text that you are inputting here?

[revblueldd]

I did in my example "/chat what about this?" but this interface is also applying the style so you can't see it. The word "this" is surrounded by asterisks in my example.

[plon]

That's odd. It works for me.

[revblueldd]

After the latest git pull it is now working for me as well.

I just got this exception again. I have no clue what might be causing it.

The above exception was the direct cause of the following exception:

The user above reposted the same /chat as in the screenshot afterwards, and it worked that time. I cannot pin down any reason why it is intermittent like that.

The only people who were trying this at this time were myself and one other (and not simultaneously), so I do not think that concurrency is the issue.

Right after it worked again, it then failed twice and worked the 3rd time after a reset. The reset may have helped but am not confident of that. This may well be an issue with the projects this is based on and nothing you can do about that part, other than perhaps some error handling to display a graceful message when the call fails.

[plon]

This is most likely an issue with the reversed Bard API that the bot uses.

[revblueldd]

I agree - perhaps could put a generic error similar to the other one, when the call fails?
