What happened?

Bolt Card Payment via POS App fails with [{"path":"payLink","message":"Invalid Uri value"}]

How did you encounter this bug?

Activated NFC payment on POS checkout and scanned BoltCard.

Relevant log output

`[{"path":"payLink","message":"Invalid Uri value"}]`

What browser do you use?

Chrome 107.0.5304.141 on Android 11

Additional information

I am regularly testing NFC payment since version 1.0.5 release of the plugin on different devices and having trouble to make it work consistently. Another thing that happens it that when scanning the NFC card another app like breeze opens and tries do a withdraw. Using the same BoltCard I have none of these problems using LNBits TPOS. Maybe it would help to check how they use the NFC Browser API: https://github.com/lnbits/lnbits/blob/main/lnbits/extensions/tpos/templates/tpos/tpos.html

I’m on it. Will fix tomorrow

Yes it would make sense to just ignore payLink if empty rather than fail. I will look at resolving our end too (CoinCorner) to not return payLink in the response if it’s empty.
