content-type altered

[bchr02]

Using Unirest, I am trying to upload a PDF file to a third party program. This third party program requires the Content-Type to be set like so: application/pdf;name=test.pdf however when I inspect the network traffic I see that Unirest is removing ;name=test.pdf from the Content-Type so that it is only sent with application/pdf. Is there any way to prevent this?

Here is the full code:

const unirest = require('unirest');
const fs = require('fs');
const path = require('path');

var Request = unirest.post('http://192.168.1.200:95/Insert');

Request
.attach('remote file', fs.createReadStream(path.join(__dirname, 'test.pdf'))) // Attachment
.headers({
    'Content-Type': 'application/pdf;name=test.pdf',
})
.end(function (response) {
    console.log(response.body);
});
