org.openqa.selenium.InvalidArgumentException: Exception while reading JSON

[vnuta9]

I am using appium ver2.0.0-beta66,
java-client ver8.5,
node ver 18.15.0;
selenium-java ver 4.9.1;
selenium-server ver3.141.59;
JDK 1.15-02 on a Mac Ventura ver13.3.1a testing a Flutter app.

Enabled appium plug-ins gestures and element-wait
I was trying to do a swipe action using PointerInput, Sequence classes
Exactly at a place I am calling a swipe action, and at the end calling driver.perform(ImmutableList.of (swipe)), I am getting the error

	at pages.BasePage.swipeJlipp(BasePage.java:905)

The line 905 in BasePage.java is from this method:

    protected void swipeJlipp(Point start, Point end, Duration duration) {
        boolean isAndroid = params.getPlatformName().equalsIgnoreCase("Android");

        PointerInput input = new PointerInput(PointerInput.Kind.TOUCH, "finger");
        Sequence swipe = new Sequence(input, 1);
        swipe.addAction(input.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), start.x, start.y));
        swipe.addAction(input.createPointerDown(PointerInput.MouseButton.LEFT.asArg()));
        if (isAndroid) {
            duration = duration.dividedBy(ANDROID_SCROLL_DIVISOR);
        } else {
            swipe.addAction(new Pause(input, duration));
            duration = Duration.ZERO;
        }
        swipe.addAction(input.createPointerMove(duration, PointerInput.Origin.viewport(), end.x, end.y));
        swipe.addAction(input.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));
        swipe.addAction(input.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));
        driver.perform(ImmutableList.of(swipe));// <<<<<<<<==== error thrown at this line.
    }

Interestingly another one step preceding this, another swipe method ran perfectly fine

    public void swipeOrScrollUpQuarterBySequence() {
        Dimension size = getWindowSize();//driver.manage().window().getSize();
        int startX = size.getWidth() / 2;
        int startY = size.getHeight() / 2;
        int endX = startX;
        int endY = (int) (size.getHeight() * 0.25);
        PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger");
        Sequence sequence = new Sequence(finger, 1)
                .addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), startX, startY))
                .addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg()))
                .addAction(new Pause(finger, Duration.ofMillis(200)))
                .addAction(finger.createPointerMove(Duration.ofMillis(500), PointerInput.Origin.viewport(), endX, endY))
                .addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));

        driver.perform(Collections.singletonList(sequence));
    }

What is the root cause of this problem ? Incompatibilities of components used ?

Thanks for your help

My bad.
Apart from reason for the error, the page swipe is working now. The basic reason is that the page is long list of data and it took 30 sec to fully load the whole page. When I incorporated the wait for that period before calling the swipe(), the swipe worked fine, and no error thrown.

We can close this issue, except for the reason for throwing the error.
Sorry for the inconvenience.
