Parse error while uploading images from Xios

Question

I’m trying to send images via POST method in Xios, but when I run the script, it gives me this error:

  error:
       { code: 500,
         error_id: 'server_error',
         description: 'Error parsing request into form data' } } }

My script

var app = require('express')();

var fs = require('fs');
var axios = require('axios');


var param = { 
    images_file: fs.createReadStream( __dirname + '/robot_orthographic.jpg')
}

axios({
    method: 'POST',
    url: 'https://gateway.watsonplatform.net/visual-recognition/api/v3/classify?version=2018-03-19',
    param,
    config: { 
        headers: {'Content-Type': 'multipart/form-data' }
    },
    auth: {
        username: 'apiKey',
        password: 'KEY'
    }
}).then(function(response){
    console.log(response.data);
}).catch(function(err){
    console.log(err);
});


app.listen(3000, function(){
    console.log('servidor rodando!');
});

I’ve tried using the lib form-data but still with the same mistake.
