I also have concerns that this may cause untrusted code to be executed. This exception seems to indicate that the plugin is attempting to evaluate the content of the triple brace as some sort of code. If a user dumps a large project into the plugin's context, and that project contains a triple brace somewhere, can this result in arbitrary code execution? It's one thing for LLMs to generate bad code, but if simply sending a message to an LLM causes code execution, that's a major issue.

I might also suggest enabling private reporting for issues like this.

Thanks for reporting, I can reproduce this error. I think it has something to do with prompt/response window. I also enabled the private reporting feature, thanks for this suggestion.
