Can't create NewRemote

[IvanBiv]

My code:

package main

import (
	"fmt"
	"os"
	"strings"
	"time"

	//"h12.io/socks"

	"github.com/tebeka/selenium"
)

func main() {
	// Start a Selenium WebDriver server instance (if one is not already
	// running).
	const (
		// These paths will be different on your system.
		seleniumPath     = "vendor/selenium-server-standalone-3.141.59.jar"
		geckoDriverPath  = "vendor/geckodriver-v0.26.0-linux64/geckodriver"
		chromeDriverPath = "vendor/chromedriver_linux64"
		port             = 8180
	)
	opts := []selenium.ServiceOption{
		selenium.StartFrameBuffer(),           // Start an X frame buffer for the browser to run in.
		selenium.GeckoDriver(geckoDriverPath), // Specify the path to GeckoDriver in order to use Firefox.
		//selenium.ChromeDriver(chromeDriverPath), // Specify the path to GeckoDriver in order to use Firefox.
		selenium.Output(os.Stderr), // Output debug information to STDERR.
	}
	selenium.SetDebug(true)
	service, err := selenium.NewSeleniumService(seleniumPath, port, opts...)
	if err != nil {
		panic(err) // panic is used only as an example and is not otherwise recommended.
	}
	defer service.Stop()

	// Connect to the WebDriver instance running locally.
	caps := selenium.Capabilities{"browserName": "firefox"}
	//caps := selenium.Capabilities{"browserName": "chrome"}

	// chromeCaps := chrome.Capabilities{
	// 	Path:            "/path/to/chrome-binary",
	// 	ExcludeSwitches: []string{"enable-automation"},
	// }
	// caps.AddChrome(chromeCaps)

	wd, err := selenium.NewRemote(caps, fmt.Sprintf("http://localhost:%d/wd/hub", port))
	if err != nil {
		panic(err)
	}
	defer wd.Quit()

	// Navigate to the simple playground interface.
	if err := wd.Get("http://play.golang.org/?simple=1"); err != nil {
		panic(err)
	}

	// Get a reference to the text box containing code.
	elem, err := wd.FindElement(selenium.ByCSSSelector, "#code")
	if err != nil {
		panic(err)
	}
	// Remove the boilerplate code already in the text box.
	if err := elem.Clear(); err != nil {
		panic(err)
	}

	// Enter some new code in text box.
	err = elem.SendKeys(`
		package main
		import "fmt"
		func main() {
			fmt.Println("Hello WebDriver!\n")
		}
	`)
	if err != nil {
		panic(err)
	}

	// Click the run button.
	btn, err := wd.FindElement(selenium.ByCSSSelector, "#run")
	if err != nil {
		panic(err)
	}
	if err := btn.Click(); err != nil {
		panic(err)
	}

	// Wait for the program to finish running and get the output.
	outputDiv, err := wd.FindElement(selenium.ByCSSSelector, "#output")
	if err != nil {
		panic(err)
	}

	var output string
	for {
		output, err = outputDiv.Text()
		if err != nil {
			panic(err)
		}
		if output != "Waiting for remote server..." {
			break
		}
		time.Sleep(time.Millisecond * 100)
	}

	fmt.Printf("%s", strings.Replace(output, "\n\n", "\n", -1))

	// Example Output:
	// Hello WebDriver!
	//
	// Program exited.
}

If I sat "geckoDriverPath = "vendor/geckodriver-v0.26.0-linux64/geckodriver"": I take at line "selenium.NewRemote(...":

                "lineNumber": 834

if I sat line "geckoDriverPath = "vendor/geckodriver-v0.26.0-linux64"", than output:

What's the matter? How to find the cause of the error?
