Hallo,

bitte schaue mal in die Logs von Shopware, ob dort ein Fehler zu finden ist.&nbsp;

Wenn man den Fehler bekommt wie mein:

&nbsp;

PayPal: Could not register webhooks due to a communication failure {“message”:"Client error response

&nbsp;

Wo genau und was muss ich ändern und an wenn kann man sich da wenden?

Hallo @kids‍

schau mal in die Shopware Log-Dateien über das File-System. Dort wirst du eine ausführlichere Fehlermeldung finden.

Servus,

wir haben den gleichen Fehler. Im Log steht folgende Fehlermeldung:

[2018-11-06 09:09:07] plugin.ERROR: PayPal: Could not register webhooks due to a communication failure {“message”:“Client error response [url] [https://api.paypal.com/v1/notifications/webhooks](https://api.paypal.com/v1/notifications/webhooks) [status code] 400 [reason phrase] Bad Request”,“payload”:"{“name”:“WEBHOOK\_URL\_ALREADY\_EXISTS”,“message”:“Webhook URL already exists”,“debug\_id”:“3004ffac8e8f2”,“information\_link”:"[https://developer.paypal.com/docs/api/webhooks/#errors",“details”:[],“links”:[]}"](https://developer.paypal.com/docs/api/webhooks/#errors%22,%22details%22:%5B%5D,%22links%22:%5B%5D%7D%22)} {“uid”:“28cb44c”}

Cache komplett geleert, Webhook über Einstellungen neu registriert.

Express-Checkout über Buttton beim Artikel/Modalwarenkorb klappt. Nur beim “regulären” Checkout mit Adressdateneingabe, Zahlungsartauswahl erscheint der Fehler. :-/

</div>

Das ist aber ein anderer Fehler, der nichts mit den Zahlungen im Frontend zu tun hat - hast du mal das “erweiterte Logging” im Plugin konfiguriert? Im Anschluss genau die Uhrzeit vergleichen, an der der Fehler entstanden ist.

Ich hab das aktiviert. Es wird kein Fehler geloggt. Hab das Log komplett geleert und den Fehler 5mal reproduziert. Kein Eintrag! :-/

Wenn das Plugin einen Fehler im Frontend ausgibt, und ein verstümmelter Log im Backend vorhanden ist, gibt es unter /var/log/ auch eine Datei&nbsp;mit Tagesdatum (da holt sich das Backend den Fehler nämlich her)&nbsp;- für heute:&nbsp; **plugin\_production-2018-11-06.log**

Ich meinte damit das Datei-Logging. Dort wurde nur eine Datei mit dem Eintrag oben geschrieben.

Hallo zusammen, ich habe auch den PayPal: Could not register webhooks due to a communication failure {„message“:"Client error response Fehler.

Hier sehe ich uzum einen diskrepanzen in der webhook url:

Lt.Backend-Log: [https://www.DOMAIN.de/PaypalUnifiedWebhook/execute](https://www.DOMAIN.de/PaypalUnifiedWebhook/execute)  
Lt. Anleitung: ‚[https://example.com/paypal\_unified\_webhook/execute](https://example.com/paypal_unified_webhook/execute)‘ ( [https://community.shopware.com/Plugin-PayPal-Produkte\_detail\_2074\_741.html#Konfiguration\_der\_API\_Einstellungen](https://community.shopware.com/Plugin-PayPal-Produkte_detail_2074_741.html#Konfiguration_der_API_Einstellungen) )

Außerdem besagt die Logfile folgendes:  
[2018-11-06 11:51:29] plugin.ERROR: PayPal: Could not register webhooks due to a communication failure {„message“:„Client error response [url] [https://api.paypal.com/v1/notifications/webhooks](https://api.paypal.com/v1/notifications/webhooks) [status code] 400 [reason phrase] Bad Request“,„payload“:"{„name“:„WEBHOOK\_URL\_ALREADY\_EXISTS“,„message“:„Webhook URL already exists“,„debug\_id“:„3659ec737737“,„information\_link“:"[https://developer.paypal.com/docs/api/webhooks/#errors",„details“:[],„links“:[]}"](https://developer.paypal.com/docs/api/webhooks/#errors%22,%22details%22:%5B%5D,%22links%22:%5B%5D%7D%22)} {„uid“:„543e13a“}

Bei einer Plugin neuinstallation kam folgender fehler:

An exception occurred while executing ‚SELECT t0.id AS id\_1, t0.name AS name\_2, t0.description AS description\_3, t0.template AS template\_4, t0.class AS class\_5, t0.`table` AS table\_6, t0.hide AS hide\_7, t0.additionaldescription AS additionaldescription\_8, t0.debit\_percent AS debit\_percent\_9, t0.surcharge AS surcharge\_10, t0.surchargestring AS surchargestring\_11, t0.position AS position\_12, t0.active AS active\_13, t0.esdactive AS esdactive\_14, t0.mobile\_inactive AS mobile\_inactive\_15, t0.embediframe AS embediframe\_16, t0.hideprospect AS hideprospect\_17, t0.action AS action\_18, t0.pluginID AS pluginID\_19, t0.source AS source\_20, t21.id AS id\_22, t21.paymentmeanID AS paymentmeanID\_23, t21.connect\_is\_allowed AS connect\_is\_allowed\_24, t21.viison\_datev\_debtor\_account AS viison\_datev\_debtor\_account\_25, t21.viison\_datev\_clearing\_account AS viison\_datev\_clearing\_account\_26, t21.viison\_datev\_period\_of\_payment AS viison\_datev\_period\_of\_payment\_27, t21.swag\_paypal\_unified\_display\_in\_plus\_iframe AS swag\_paypal\_unified\_display\_in\_plus\_iframe\_28, t21.swag\_paypal\_unified\_plus\_iframe\_payment\_logo AS swag\_paypal\_unified\_plus\_iframe\_payment\_logo\_29, t21.paymentmeanID AS paymentmeanID\_30, t0.pluginID AS pluginID\_31 FROM s\_core\_paymentmeans t0 LEFT JOIN s\_core\_paymentmeans\_attributes t21 ON t21.paymentmeanID = t0.id WHERE t0.name = ? LIMIT 1‘ with params [„SwagPaymentPayPalUnified“]: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‚t21.swag\_paypal\_unified\_display\_in\_plus\_iframe‘ in ‚field list‘

Nach der neuinstallation mit neuer PayPal RestAPI-APP (Neue Zugangsdaten ohne eingerichteten Webhook) wird durch das Plugin der entsprechende Hook bei Paypal registriert undzwar auf [https://www.DOMAIN.de/PaypalUnifiedWebhook/execute](https://www.DOMAIN.de/PaypalUnifiedWebhook/execute) . Jedenfalls anderes als in der Anleitung. Es scheint auch, dass der Fehler (s.o.) nach änderungen in den Plugin-einstellungen auftritt. („Webhook URL already exists“)

Bei mir taucht das gleiche Problem auf. Es läßt sich kein Plug-in mehr deaktivieren oder deinstallieren. Immer taucht die Datenbankfehlermeldung auf, die Herzschlag oben schon gepostet hat.

Habt ihr das irgendwie lösen können?
