TypeError: Cannot read property 'name' of null NodeJs Request module

Question

I want to send a post request with the request module. And my code snipped like that:

 let formData = new FormData();

   myArray.map((param, index) => {
      formData.append(param.name, param.value)
    })

    formData.append('file', fs.createReadStream(file.location), { filename: file.name });

    var options = {
      'method': 'POST',
      'url': 'https://shopify-video-production-core-originals.s3.amazonaws.com/',
      'headers': {
      },
      formData: formData,
    };

    let requestProm = async () => {
      return new Promise(resolve => {
        request(options, function (error, response) {
          if (error) {
            logger.error("Video Upload Failed")
            console.log(error)
          } else {
            logger.info("Video Upload Successfull");
            resolve(response);
          }
        })
      })

    }

    await requestProm()

But I getting an error as :

TypeError: Cannot read property 'name' of null

Why Im getting this error? Please Help!

Edit: I controlled my formData. There is no null name value. I searched on internet but I cannot find any solution. So, My formData is like that:

  _valueLength: 832,

Well yes, you wrote `{ filename: file.name }` but `file` is undefined. — Jeremy Thille, Jan 13 '22 at 16:11

Apparently, form-data is already handled by request-promise. You can pass the form-data as an object. Check this

Cannot read property '' of null means that the property of the object doesn't exist. What you can do is log file and then check if the property 'name' exist. Remember: console.log() is your best friend in nodejs (and in programming in general)

It means that "file" is equal to null, which has no properties. – James Jan 13 '22 at 16:40
