Closed a-abir closed 2 months ago

🔍 Before submitting the issue

🐞 Description of the bug

fluent.exit() only drops the connection; check_health() ==> "NOT_SERVING" not closed

_fluent.tui.closefluent() _fluent.executetui(command="/close-fluent") -- variants hangs the application

With fluent.tui.exit()

HOW DO I CLOSE OUT and keep generated results ???
