Beginnen Sie damit, den Prompt-Fehler mit Q version 1.12.7 unter macOS 15.5 im VSCode-zsh-Terminal zu reproduzieren, nachdem Sie wie berichtet q doctor und q restart ausgeführt haben. Es werden keine Quelldateien, Tests oder Reproduktionsschritte genannt; abgeschlossen ist die Untersuchung, wenn geklärt ist, warum die nächste Nachricht InternalServerError zurückgibt, und bestätigt wurde, dass ein Prompt erfolgreich verarbeitet wird oder der Fehler verwertbare Diagnosen liefert.
