Solutions

1. Verify ~/.claude exists and is readable by the process user
2. Check the console output 'Error getting Claude session info:' for the root cause
3. Run the CLI once normally so Claude Code materializes its config/session files
4. Retry after closing other processes writing to ~/.claude

const exists = await fs.promises.access(path.join(os.homedir(), '.claude'), fs.constants.R_OK).then(() => true).catch(() => false);

try { const s = await getSession(); } catch (e) { if (e.response?.status === 500) return { available: false, reason: 'session-info-unavailable' }; throw e; }

When it happens

Trigger: GET /api/session when ~/.claude config files are missing/malformed, or session-state files cannot be read (permissions, concurrent write).

Common situations: Fresh machine where Claude Code hasn't created config yet; permissions changed on ~/.claude; running analytics as a different user than the one using Claude Code.
