Version: 2.1.120 (Claude Code)
Platform: Windows 11 Home, PowerShell
Steps to reproduce
- Have a previous Claude Code session
- Run
claude --resumefrom the terminal
Error
ERROR FKH is not a function. (In 'FKH(K)', 'FKH' is undefined)
B:/~BUN/root/src/entrypoints/cli.js:9273:5663
Root cause (analyzed)
onSessionRestored (mangled as FKH) is destructured from XJ7({enabled: S, ...}) where S is always false in CLI mode (const S = useMemo(() => false, [])). The function returns undefined for that callback, but it is called unconditionally when initialMessages (K) has length > 0 during session restoration:
useEffect(() => {
if (K && K.length > 0)
sW8(K, Kq()), GMq(...), BIq(K), pc(K), oMH.current.current = I38(K, Fq), FKH(K) // FKH is undefined
}, []);
Expected behavior
Session resumes normally.
Actual behavior
CLI crashes immediately on --resume — session cannot be restored.
