在使用 Discord Persona Bot 时，我发现了一个错误（并创建了一个 PR 来修复它）
Job exception: context must be an instance of BotContext
/var/www/discourse/plugins/discourse-ai/lib/personas/bot.rb:55:in `reply'
/var/www/discourse/plugins/discourse-ai/lib/discord/bot/persona_replier.rb:25:in `handle_interaction!'
/var/www/discourse/plugins/discourse-ai/app/jobs/regular/stream_discord_reply.rb:13:in `execute'

**What is the problem?**
When using the Discord integration in `persona` mode (… `SiteSetting.ai_discord_search_mode == "persona"`), triggering a slash command causes the background job to fail.
The `DiscourseAi::Discord::Bot::PersonaReplier` was passing a raw `Hash` to the `DiscourseAi::Personas::Bot#reply` method. However, `Bot#reply` enforces that the input must be an instance of `DiscourseAi::Personas::BotContext`.
**What is the fix?**
I updated `handle_interaction!` in `lib/discord/bot/persona_replier.rb` to correctly initialize a `BotContext` object with the user query and options before passing it to the bot.
I've learned this by seeing it on https://github.com/discourse/discourse/blob/main/plugins/discourse-ai/app/jobs/regular/stream_discover_reply.rb#L36-L41

Here's a little proof of it working on my Discord test server
