我正在使用Express为用户注册创建一个API端点。问题是，每当我向该API端点发送一个将引发错误的请求时，我的node.js服务器就会崩溃并给我以下消息：

node:internal/errors:491
[1]     ErrorCaptureStackTrace(err);
[1]     ^
[1]
[1] Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent 
to the client
[1]     at new NodeError (node:internal/errors:400:5)
[1]     at ServerResponse.setHeader (node:_http_outgoing:663:11)
[1]     at ServerResponse.header (D:\...\node_modules\express\lib\response.js:794:10)
[1]     at ServerResponse.send (D:\...\node_modul

因此，node.js服务器在发送错误（失败）响应时会崩溃，但在发送成功响应时不会崩溃。所以我想我在这里没有正确地处理错误？
我做错了什么？下面是我的实现：

const registerUser = async (req: Request, res: Response) => {
  try {
    const userData = createUserSchema.parse(req.body) as User;

    const salt = await bcrypt.genSalt(10);
    const hashedPassword = await bcrypt.hash(userData.password, salt);

    const user = await db.user.create({
      data: {
        ...userData,
        password: hashedPassword,
      },
    });

    return res.status(201).json({
      status: 'success',
      data: { name: user.name, email: user.email },
    });
  } catch (error) {
    if (error instanceof z.ZodError) {
      return res.status(422).json({
        status: 'fail',
        message: error.issues,
      });
    } else if (error instanceof Prisma.PrismaClientKnownRequestError) {
      if (error.code === 'P2002') {
        return res.status(409).json({
          status: 'fail',
          message: 'Email address is already in use',
        });
      }
    }

    return res.status(500).json({
      status: 'fail',
      message: 'Something went wrong',
    });
  }
};

我尝试只在一种情况下返回error，看看这些响应是否冲突，但即使我只有一个响应，node.js服务器也会崩溃。
