This error typically happens when I try to perform a gesture action like swipe, drag, or flick.

package Tests;

import java.util.HashMap;  
import java.util.Map;

import org.testng.annotations.Test;

import Keys.TestKeys;  
import Pages.Customer;  
import basetest.BaseTest;  
import io.github.ashwith.flutter.FlutterElement;  
import io.github.ashwith.flutter.FlutterFinder;

public class customerTest extends BaseTest {

```
@Test
public void Scroll() throws InterruptedException {
	Customer custom = new Customer(driver);

	custom.tapCustomerModule();

	FlutterFinder finder = new FlutterFinder(driver);
	Thread.sleep(5000);
	FlutterElement customerList = finder.byValueKey(TestKeys.customerListPageTestKeys.customerList);

	// Build finder JSON for the scrollable element
	Map<String, Object> finderJson = new HashMap<>();
	finderJson.put("finderType", "ByValueKey");
	finderJson.put("keyValueString", customerList);
	finderJson.put("keyValueType", "String");

	// Build scroll command with proper params
	Map<String, Object> scrollCommand = new HashMap<>();
	scrollCommand.put("finder", finderJson);
	scrollCommand.put("dx", 0);
	scrollCommand.put("dy", -300);
	scrollCommand.put("durationMilliseconds", 500);
	scrollCommand.put("frequency", 60);

	// Execute scroll
	driver.executeScript("flutter:scroll", scrollCommand);

	Thread.sleep(2000); // wait to observe scroll
}

```

}

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Cannot destructure property ‘dx’ of ‘opts’ as it is undefined.

I see this is working now, posting in case someone has the same error and is looking for the solution:

> private void performScroll(FlutterElement element, int dx, int dy, int duration,… int frequency) {
> // Print scroll parameters for debugging

> scrollParams.put("dx", 0);
> scrollParams.put("dy", -300);
> scrollParams.put("duration", 200);
> scrollParams.put("frequency", 60);
> scrollParams.put("scrollableId", element.getId());
>         
> System.out.println("Scroll params: " + scrollParams);

> driver.executeScript("flutter:scroll", scrollParams);
