Happening again for Samsung Galaxy S21 5G , Android 11

[chr-stripe]

Hi @piotrekBDS, can you try updating to SDK 4.1.0? We believe the issue you're running into is fixed in that version.

[piotrekBDS]

Well, the 4.1.0 version changed the whole card payment sheet we are using in other place and I cannot do that as for now. Is there any way (version) to use "old" card payment sheet and have the t2p issue fixed?

[chr-stripe]

Can you elaborate on which changes you're referring to? I don't believe there have been any updates to the visuals of the Tap to Pay payment screen in 4.1.0.

[piotrekBDS]

@chr-stripe thank you, sorry for the confusion, seems like we had wrong SDKs setup there.
We are about to test 4.1.0. I will let you know/close the task if things are alright. Thanks!

[piotrekBDS]

@chr-stripe after upgrade to 4.1.0 and another round of tests we are observing same exception being thrown, in different place though (code below). Shall we create separate issue for this?

[chr-stripe]

Can you provide a Payment Intent ID where you're seeing this error occur on? I will try to check our internal logs to investigate further.

Additionally, are you able to reproduce this locally, or have an idea of which kind of card(s) this is occurring on? Any information on how you are testing this will be helpful 🙂

[piotrekBDS]

We set the device up a few minutes ago, Galaxy s20+, android 11. This happens even before the card payment is collected, before T2P UI is displayed

Hi @piotrekBDS, sorry for the delayed response. Would you be able to send me the stacktrace you're seeing as text instead of in a screenshot? Additionally, what is the frequency you're seeing of this bug – is it happening multiple times a day? Are you able to reproduce it locally through any means?

I pasted another one, the first you can see at the top of the discussion.

It happens for some devices only, and it's reproduceable on them, quite often.

[piotrekBDS]

@chr-stripe have you been able to analyze the above?

[chr-stripe]

Hi @piotrekBDS, thank you for the additional info earlier! We implemented a fix for this in the Tap to Pay SDK which will be rolling out in the 4.3.0 release. We identified that this is related to unexpected formatting of the device's model name, which would explain why it happens only on some devices, but consistently on those devices.

In the SDK, this error can occur when we try to parse the device's model name to determine where the NFC logo should be placed. This could be worked around by calling Terminal.setTapToPayUxConfiguration() for those devices to hardcode the NFC tap zone position for those devices, if you like. Otherwise, the fix for this issue will be present in the 4.3.0 SDK and will be mentioned in the release notes for that update.

[piotrekBDS]

Thank you @chr-stripe for your reply. We will wait for 4.3.0 and update it 👍
