Inizia da crates/chat-cli/src/cli/chat/mod.rs:1647 e analizza il fallimento della richiesta segnalato dopo q doctor e q restart. Riproduci l'errore profileArn su Linux Mint 22.3 con la versione 1.28.2, quindi verifica che un utente autenticato con un profilo selezionato possa ricevere una risposta senza l'errore.
