ChatBot generates an exception when Chatbot.converse is invoked

[dcpetty]

Describe the bug

When using the Story GPT Hour of Code activity (https://aif.to/2024-hoc-storygpt) a student generated an exception when invoking that function whose message was (something like): 'ChatBot failed to return response: missing field @ line 24 column 5.' Only one out of 18 students exhibited this behavior. I do not know what the question field was that they submitted.

Affects

• Designer
• Blocks editor
• Projects Explorer
• Companion
• Compiled apps
• Buildserver
• Debugging
• Other... (please describe)

Running the app in AI Companion

Expected behavior

ChatBot returns a response. No exception is generated.

Steps to reproduce

When it was happening, all they needed to do was invoke ChatBot.converse. (This is after the fact, so it will probably be difficult to reproduce.)

@dcpetty Do we know which backend they were using? IIRC, Gemini sometimes doesn't return a response when it might respond with objectionable content. @jisqyv might recall better.

Definitely Gemini. I do not know what the prompt was.
