Error Message

I am receiving a 403 Forbidden error with the status PERMISSION_DENIED when trying to send a simple message (e.g., "hello") in the Gemini CLI. Error Details from Debug Console: I noticed a yellow warning banner at the top stating: "We're making changes to Gemini CLI that may impact your workflow... adding more robust detection of policy-violating use cases." This error started appearing after these changes.

TL;DR

The 403 Forbidden error with PERMISSION_DENIED status may be related to recent changes in the Gemini CLI, and checking the policy-violating use cases detection or reaching out to support might help resolve the issue.
