claude-code - 💡(How to fix) Fix --continue crashes with "g9H is not a function" on 2.1.120 (macOS arm64) [1 comments, 2 participants]

Summary

In version 2.1.120, running claude --continue immediately throws an unhandled error and the CLI exits. Running claude without --continue works fine. 2.1.119 does not have this issue. The error reproduces deterministically.

Environment

• Claude Code: 2.1.120 (auto-updated 2026-04-25, install via the Bun-bundled binary at ~/.local/share/claude/versions/2.1.120)
• macOS: 26.2 (build 25C56), Apple Silicon (arm64)
• Shell: zsh
• Plugins enabled in settings.json: clangd-lsp@claude-plugins-official
• skipDangerousModePermissionPrompt: true

Steps to reproduce

1. Have at least one previous session in the current project (so there is something to continue).
2. Run:

   claude --continue --dangerously-skip-permissions

3. Crash before any UI is rendered.

Error

ERROR  g9H is not a function. (In '''g9H(K)''', '''g9H''' is undefined)

Likely cause (from reading the minified source)

In Ub8 (REPL component), the FXK hook is called with enabled: S, where S is hardcoded:

let S = s_.useMemo(() => !1, []);
...
let { onBeforeQuery: F9H, onTurnComplete: ZLH, onSessionRestored: g9H,
      render: aM_, ownsInput: LLH } = FXK({ enabled: S, ... });

Because enabled is false, FXK returns an object whose onSessionRestored is undefined. But shortly afterwards there is an unconditional call:

s_.useEffect(() => {
  if (K && K.length > 0) {
    HP_(K, K8());
    hY8({ abortController: new AbortController, taskRegistry: YH });
    tC8(K);
    UQ(K);
    sYH.current.current = xz_(K, g8);
    g9H(K);   // <-- crashes when initialMessages is non-empty and enabled=false
  }
}, []);

K is initialMessages, which is non-empty exactly when --continue (or --resume) loaded a prior session. So any user with a prior session hits this on --continue.

Suggested fix: guard the call (g9H?.(K)), or only attach the effect when enabled.

Workaround

Roll back to 2.1.119:

ln -sfn ~/.local/share/claude/versions/2.1.119 ~/.local/bin/claude
