KeyError가 발생합니다

안녕하세요.

채굴 매뉴얼을 보고 서버설정 완료하고 구동을 하면 아래 에러가 발생하며 멈춰있는 것 같습니다.

sawtooth-validator-default | Traceback (most recent call last):
sawtooth-validator-default | File “/usr/lib/python3/dist-packages/sawtooth_validator/networking/future.py”, line 79, in run_callback
sawtooth-validator-default | self._callback_func(self._request, self._result)

어떻게 하면 해결이 될까요?
