Summary

TypeError: Cannot read property 'name' of undefined

Simplest Example to Reproduce

request.post({
    url: '/cdn/upload',
    formData: {
        // Pass a simple key-value pair 
        my_field: 'my_value',
        // Pass data via Buffers 
        my_buffer: new Buffer([1, 2, 3]),
        // Pass data via Streams 
        my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
        // Pass multiple values /w an Array 
        attachments: [
            fs.createReadStream(__dirname + '/attachment1.jpg'),
            fs.createReadStream(__dirname + '/attachment2.jpg')
        ],
        // Pass optional meta-data with an 'options' object with style: {value: DATA, options: OPTIONS} 
        // Use case: for some types of streams, you'll need to provide "file"-related information manually. 
        // See the `form-data` README for more information about options: https://github.com/form-data/form-data 
        custom_file: {
            value:  fs.createReadStream('/dev/urandom'),
            options: {
            filename: 'topsecret.jpg',
            contentType: 'image/jpeg'
            }
        }
