Hi,  
I am trying to record the steps on mobile testing where my mobile is connected via usb and I am using vysor to work with katalon for mobile testing. While recording, I tapped on my mobile’s screen, but I am unable to do so. I am getting this error:

```auto

Hi,

Thank you for letting us know. Can you please double-check the “Recycler View” in your script? I found this discussion about the error : [android - RecyclerView is missing - Stack Overflow](https://stackoverflow.com/questions/24441107/recyclerview-is-missing)
