AI Assistant Didn't Edit the Loop

Problem: The AI assistant fails to make any changes when asked to work with loop nodes. Despite appearing to process the request and showing progress, no actual modifications are made to the workflow.

Use Case: User attempts to use the built-in AI assistant to configure or modify loop nodes in their workflows, expecting the assistant to understand and implement the requested changes.

Proposed Solution: Improve the AI assistant's understanding of loop node architecture and ensure it can properly modify sub-branch systems. Add better error handling and feedback when the assistant cannot complete a task.
