client.Create("test.txt") error SSH_FX_OP_UNSUPPORTED

I am trying to send a file to an sftp. My assumption is that I first have to connect and then create a “client”. Correct?

But when I try to client.Create(filename) I get this error:

sftp: “FeatureNotSupported: This feature is not supported.” (SSH_FX_OP_UNSUPPORTED)

Any clue what causes this error?

package main

import (
	"fmt"
	"github.com/pkg/sftp"
	"golang.org/x/crypto/ssh"
	"io"
	"os"
	"strings"
)

func main() {
	send2ftp("./test.txt")
}

func send2ftp(filename string) {
	config := &ssh.ClientConfig{
		User: "username",
		Auth: []ssh.AuthMethod{
			ssh.Password("a_long_password"),
		},
		HostKeyCallback: ssh.InsecureIgnoreHostKey(),
	}

	conn, err := ssh.Dial("tcp", "sftp.test.com:22", config)
	if err != nil {
		if strings.Contains(err.Error(), "connection refused") {
			fmt.Println("SSH isn't up yet")
		} else {
			fmt.Println(err.Error())
		}
	}
	defer conn.Close()

	// create new SFTP client
	client, err := sftp.NewClient(conn)
	if err != nil {
		fmt.Println(err)
	}
	defer client.Close()

	// create destination file
	dstFile, err := client.Create(filename)
	if err != nil {
		fmt.Println(err)
	}
	defer dstFile.Close()

	// create source file
	srcFile, err := os.Open(filename)
	if err != nil {
		fmt.Println(err)
	}

	// copy source file to destination file
	io.Copy(dstFile, srcFile)
	if err != nil {
		fmt.Println(err)
	}
}

After hours of research I found this that solves the problem (replace client.Create):

	// create destination file
	dstFile, err := client.OpenFile(filename, os.O_WRONLY|os.O_CREATE|os.O_TRUNC)
	//dstFile, err := client.Create(filename)
	if err != nil {
		fmt.Println(err)
	}
