message repository에 객체를 하나

const msg: Message = await this.messageRepository.create({
        chatRoom: chatRoom,
        msg_content: msgContent,
        date: new Date(),
        userId: userId,
        user: user
});
await this.messageRepository.save(msg);

save 메소드를 쓸 때 이 에러가 났다.

해결

insert 메소드 사용

const msg: Message = await this.messageRepository.create({
        chatRoom: chatRoom,
        msg_content: msgContent,
        date: new Date(),
        userId: userId,
        user: user
      });
await this.messageRepository.insert(msg);
