My OpenClaw service openclaw-railway-template-easy-config in project lively-laughter is failing to start. The Gateway is crashing on every boot with 'Invalid config at /data/.openclaw/openclaw.json - channels.slack: invalid config: must NOT have additional properties.' The fix is to run openclaw doctor --fix against that specific config file path on the persistent volume, but I cannot access a terminal. Can someone exec into the container and run this command, or alternatively help me access a shell via the Railway CLI? This is blocking my production agent.
