| Summary | 0011416: kyc ready but payment denied | ||||
| Description | I created a a new server config from .deb taler-merchant 1.5.16 taler-exchange 1.5.9 kyc enabled, I wont need KYC so my workaround is turn it off and go on but strangely the default config fail with bad logs. Not sane error explaining. Looks like a bug. After all set, I withdraw some coins to the wallet and I was ready to spend it. I created a merchant server, configured to the same exchange and created an order (libeufin bank). All good. When tried to pay the order the wallet when from paying to aborted with no explanation. Digging into wallet-core logs I found 05-18 21:44:25.482 15522 15547 D taler-wallet-embedded: 2026-05-18T21:44:25.482Z pay-merchant.ts TRACE got resp {"requestMethod":"POST","headers":{"access-control-allow-origin":"*","access-control-expose-headers":"*","cache-control":"no-store","connection":"keep-alive","content-length":"334","content-type":"application/json","date":"Mon, 18 May 2026 21:44:24 GMT","server":"nginx"},"requestUrl":"https://merchant.taler.ar/orders/2026.138-02WASC87BQBDG/pay","status":451} Strange because the merchant portal doesnt say anything about KYC requirements.

Maybe the biggest issue is: * wallet should transition to a transaction state when it can retry with the same coins and the UI should say "Merchant can't process this payment right now due to legal requirments" * merchant backend should inform the same by /kyc I'm not sure what's wrong with the default configuration tho, it should be reproducible |
