Here's the full stack trace which interestingly doesn't seem to include anything Kilo Code-specific, so I'm not sure why it's being attributed to your plugin:

It's very possible this is an incorrect attribution, but I will say that I only see it when Kilo Code is installed/enabled.

Reproduction steps

Nothing specific. Just install/enable the Kilo Code plugin and this error is sometimes (often?) reported after a project is opened.
