        self.in_memory_output = RollPairConfKeys.EGGROLL_ROLLPAIR_IN_MEMORY_OUTPUT.get_with(session.get_all_options())
        if not self.default_store_type:
            raise ValueError(f'in_memory_output "{self.in_memory_output}" not found for roll pair')

判断条件错了，应该改为:

        self.in_memory_output = RollPairConfKeys.EGGROLL_ROLLPAIR_IN_MEMORY_OUTPUT.get_with(session.get_all_options())
        if not self.in_memory_output:
            raise ValueError(f'in_memory_output "{self.in_memory_output}" not found for roll pair')
