[Leimy]

Bug Description

❌ Error: HTTP error: (error http 429)

I was trying to use efrit-agent to debug what was going on with efrit-chat which now fails with:

====
You: hello

System: Thinking...

System: Failed to send request: Wrong type argument: arrayp, ("⠋" "⠙" "⠹" "⠸" "⠼" "⠴" "⠦" "⠧" "⠇" "⠏")

Not sure what changed recently. Just updated today.

Steps to Reproduce

1. Update to Efrit 0.4.1 and try to use efrit-chat.
2. Efrit-agent is failing with too many requests
