如何用ESlint修复我的Node.js语法？

Question

我添加了几行代码来检查REST API(POST方法)上的错误。第39-60行

app.post('/collections/:collectionName', (req, res, next) => {
    pino(req,res);
    req.log.info('pino output');
    try {
      req.collection.insert(req.body, {}, (e, results) => {
        if (e) return next(e)
        res.send(results.ops)     
    } catch (err) {
      if (err instanceof CustomError) {
        return res.status(err.status).send({
            error: err.code,
            description: err.message,
        }) else {
          console.error(err);
          return res.status(500).send({
            error: 'GENERIC',
            description: 'Something went wrong!!!',
        })
    }
  }
}   
})

当我跑的时候

eslint --fix index.js

/home/miki/restwitherrors/index.js
  46:7  error  Parsing error: Unexpected token catch

✖ 1 problem (1 error, 0 warnings)

如果我在VSCode,Shift+ALt+.中尝试并选择Fix all detected spelling errors

输出为

我认为你应该在打开catch之前关闭你的insert函数
