without any console error nor OS and browser version it's impossible to do anything here. also keep in mind that "(NotFoundException: No MultiFormat Readers were able to detect the code.)" also means that your barcode can also be unreadable, reason why you always need to test your scanner with many different barcodes from different sources and format.

@ROBERT-MCDOWELL iOS version 17.1.2 , Model name Iphone 13 .. I am able to read same barcode from android mobile with no issue but from iOS mobile it is not working and no error other than error when uploading barcode

again without javascript console log no way to check what's happening. also keep in mind that if it works on a previous OS / browser version it means that the issue comes always from the OS/Browser side, which you can check there first, unless there is a new javascript error due to something else. More, the camera and its focus is involved and often the issue comes from that.

@Mhussein27 You can connect your iPhone to a Macbook and get consol logs in the Safari browser.

Mhussein27 commented 9 months ago

@ipokrovkiy i did that but with no luck to open the same scanning page from mobile safari to appear at laptop safari so Cosole.log after connecting to mobile from to safari browser, shows nothing

@Mhussein27 Does it work in Chrome?

If it does not, how to debug on Chrome on mobile

In a tab open chrome://inspect/ then press Start Logging.
open another tab and connect to site
Come back anytime to see any and all console outputs!

Facing a similar issue on iPhone 13&15, nothing is being scanned.
