| Summary | 0009703: taler-exchange-wire-gateway-client --debit-history fails with 404 | ||||
| Description | I set up libeufin-bank and am working on setting up taler-exchange. In section 7.6.1 <https://docs.taler.net/taler-exchange-manual.html#exchange-bank-account-configuration> I am encouraged to run this snippet to test my setup: taler-exchange-wire-gateway-client \ --section exchange-accountcredentials-1 --debit-history This fails with 404 not found in my configuration. The libeufin-bank reports that the endpoint is unknown: Apr 07 09:41:30 taler-exchange libeufin-bank[461]: 07-Apr-2025T09:41:30.385 INFO libeufin-bank - 404 GET /history/outgoing 0ms: GENERIC_ENDPOINT_UNKNOWN There is no endpoint defined for the URL provided by the client. Check if you used the correct URL and/or file a report with the developers of the client software If I follow the manual more strictly taler-exchagne-wire-gateway-client fails with an assertions because the path in the URL does not end with a slash. I have attempted various paths with no success. The most promising is: /accounts/exchange/taler-wire-gateway/ which fails with 401 and a hint that "Authorization method 'Basic' is not supported". The account I created is called "exchange". This path was guessed by grepping libeufin source code. The assertion is this: 2025-04-07T09:42:39.348080+0200 taler-wire-gateway-client-4883 ERROR Base URL `http://taler-bank/taler-wire-gateway/Exchange' does not end with '/', cannot join with `history/outgoing?delta=-10' 2025-04-07T09:42:39.348094+0200 taler-wire-gateway-client-4883 ERROR Assertion failed at bank_api_debit.c:290. Could not request the debit transaction history. | ||||
| Additional Information | I put the "exchange" category. Other candidate categories are documentation and libeufin-bank | ||||
| Tags | No tags attached. | ||||

Yes, the example is wrong / very outdated. I have now fixed it in 006c3bbe..9017336e: - WIRE_GATEWAY_URL = https://bank.demo.taler.net/taler-wire-gateway/Exchange + WIRE_GATEWAY_URL = https://bank.demo.taler.net/accounts/exchange/taler-wire-gateway/ (Note that it might be "Exchange" still, depending on the username you used at the bank). Thanks for reporting! |

Hi! Thanks for fixing the documentation quickly. As mentioned I guessed that URL by grepping the libeufin-bank source code. However, it then fails with 401 and a body { "code": 40, "hint": "Authorization method 'Basic' not supported" } Can we address this in the same issue? |
|
|
Hmm. We can address this in the same issue, probably not at the same speed ;-). Can you try setting the PWD_AUTH_COMPAT=YES option in the libeufin-bank configuration (and re-start the bank)? *IF* that is the issue, well, then there are two fixes: 1) put this into the documentation, and 2) eventually we should implement token auth in the taler-exchange-wire-gateway-client. But it would be great if you could first confirm that that's indeed a fix. |
|
|
Thanks! Indeed, that fixed it. For my purposes (just testing) PWD_AUTH_COMPAT=YES is fine. It's unlikely I would have been able to guess this before giving up. |
|
|
taler-docs.git::70d639f6..87ff7614 documents the use of PWD_AUTH_COMPAT=YES. That doesn't *exactly* fix the bug, as we should add support for token auth to the wire gateway client. So I'll leave the bug open for that. |
|
|
taler-exchange-wire-gateway-client now supports using the (optional) CORE_BANK_URL ``/token`` endpoint to replace ``basic`` authentication with a ``bearer`` token. If this is not possible (no CORE_BANK_URL configured), a warning will be printed and the process will continue to try with just ``basic`` authentication (which may or may not be permitted by the taler-wire-gateway). |
