The RAIErrorData import is no longer used after removing the raiError state variable and its related code. This unused import should be removed to keep the imports clean.

The validation logic has a potential issue. If auth_enabled is None, calling .lower() on it will raise an AttributeError. Consider handling the None case explicitly or providing a default value before calling .lower(). For example: auth_enabled = (auth_enabled or "false").lower() if (auth_enabled or "false").lower() in ["true", "false"] else "false"

The validation only checks if the URL starts with http:// or https://, but doesn't validate the actual URL structure. A malformed URL like http:// (missing domain) would pass validation but cause issues downstream. Consider using a more robust URL validation, such as checking with urllib.parse.urlparse() to ensure it has a valid netloc component.

Purpose
This pull request introduces several improvements across the backend and frontend codebases, focusing on better error logging, enhanced security for frontend configuration, and minor code and dependency cleanups. The most significant changes include replacing silent exception handling with debug logging for agent lifecycle events, escaping environment variables before injecting them into the frontend, and removing unnecessary state management and peer dependency flags.
Backend Improvements:
lifecycle.py, replacing silent exception swallowing with informative log messages when agent registration, closing, or unregistration fails. This improves observability and troubleshooting for agent state transitions. [1] [2] [3]Frontend Improvements:
API_URL,ENABLE_AUTH) before injecting them into the frontend config to prevent potential HTML injection vulnerabilities.raiErrorstate and related code fromHomeInput.tsx, simplifying the component's state management. [1] [2] [3] [4]Dependency and Test Cleanups:
"peer": trueflag from multiple dependencies inpackage-lock.jsonto clean up the dependency tree and avoid unnecessary peer dependency warnings.
