Multiple elements matched on action Swipe.

[alissa-ferro]

Hi.
When I try to swipe a view by it's type and index detox simply ignores the index and gives me a 'Multiple UI elements matched for the criteria' error .
I don´t have access to the apps code so I can´t put a testId on the view.

My code:

await element(by.type('UINavigationTransitionView')).atIndex(0).swipe('right', 'fast');

error:

1. Test:
   Error: Error: Multiple UI elements matched for the given criteria.
   Exception with Action: {
   "Action Name" : "Swipe Right for duration 0.1",

I was just about to report the same, but for scrollTo instead of swipe.

I'm having problem with this:
await element(by.type('RCTScrollView')).atIndex(0).scrollTo('bottom');

I get "Multiple elements were matched"

But this is okay:
await expect(element(by.type('RCTScrollView')).atIndex(0)).toBeVisible();

[akuschqa]

I have the same issue with nested scrollView:

const scrollView = element(by.id('scene.id.base').and(by.type('RCTScrollView'))).atIndex(0);
await expect(scrollView).toBeVisible();
await expect(scrollView).toExist();

toBeVisible and toExist work properly, but scroll/scrollTo/swipe do not work:

await scrollView.scroll(100, 'down');
A part of the logs:

Error Trace: [
  {
    "Description" : "Multiple elements were matched: (
    "<RCTCustomScrollView:0x7fb877a6d400; AX=N; AX.frame={{0, 110}, {375, 517}} <...>

I think there are generally problems around matching scrollviews. I'm also keeping an eye on this one: #164

This might be a dupe of #164, but I think this is still relevant.

Still not working on latest Detox.

I can confirm this is still not working.

scroll, scrollTo, swipe ignore atIndex(0). Though tap regards atIndex(0).

The fact that @ma-pe found different behaviours in tap and other actions is pretty odd.
The implementation is generic for all actions, and the underlying EarlGrey implementation seems generic as well.

1. Do you have a demo project we can test this on ?
2. If not, it would be super helpful, either by adding failing tests to detox test suite, or creating a different project.
3. If all that is impossible, can you at least paste verbose log of those tests fail, I would like to see the constructed invocation json passed to the device.

The issue has been closed for inactivity.

unstale unclose.

I'll try to setup something for reproducing the issue in the next days.

Multiple elements issues have been resolved recently. Please try a new build and if it still occurs, open a new issue, rather than bumping an old one. Thanks
