Hi, I want to find a way to any correspondance about this both field title & description from my Jobs db, to compare other contains on my list potentialJobs

My Jobs database fields:

DPMUB
DPMUB722×374 44.8 KB

I thinking my probleme provide from my variable : let correspondance = Jobs.find({title: req.body.title , description: req.body.description})

I inquired everywhere, and it seems req.body. be the default value to find any match in all fields

but when i try to run it i got that :

ReferenceError: req is not defined
    at Timeout.apiToDB [as _onTimeout] (/Users/mac/Desktop/server/config/job.js:49:53)
    at listOnTimeout (internal/timers.js:557:17)
    at processTimers (internal/timers.js:500:7)
[nodemon] app crashed - waiting for file changes before starting...

My code Job.js :

function apiToDB() {

let correspondance = Jobs.find({title: req.body.title , description: req.body.description})

const potentialJobs = [{ title: 'Electrotechnicien H/F' }, description: 'blabla'
  {
  title: 'Assistant Medical H/F',
  description: '12345....',
  },
  { title: 'Designer H/F', 
  description: 'ABCDE....' }];


      for (let i = 0; i < Math.min(5, potentialJobs.length); i++) {
        if (potentialJobs[i].title && potentialJobs[i].description === correspondance) {
          console.log('This job : ' + potentialJobs[i].title + ' is already exist on DB');
          continue;
        }
        else{
              var title = potentialJobs[i].title;
              var desc = potentialJobs[i].description;
              var url = potentialJobs[i].redirect_url;
              var date = new Date().toLocaleDateString("fr")

              console.log( "Job value insert :  " + title + " " + url);
    
              assignDataValue(title, desc, url, date)
            
              continue
            
        }
      }
}

If anyone can help me, Thanks a lot…
