在Magento 2.2支付订单后，自动发送发票电子邮件

Question

我试图在付款并创建发票后触发客户发票邮件。付款网关是PayPal Plus（Iways）和亚马逊工资。如果我正确理解的话，这些网关在成功处理订单后会自动创建发票。

这是我写的模块，但是激活它并清除缓存后什么都没有发生：

app/code/vendor/autosendinvoice/etc/events.xml

    <?xml version="1.0"?>
    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
        <event name="sales_order_invoice_register">
            <observer name="VendorAutoSendInvoice" instance="VendorAutoSendInvoiceObserverAutoSendInvoice" />
        </event>
    </config>

这是观察者应用/代码/供应商/autosendinvoice/observer/autosendinvoice.php

        } else {
            return false;
        }
    }
}

我没有任何错误。我在这里缺少什么？

可能存在错误：

1. 检查在管理中是否启用了发票电子邮件 - ＆gt;商店 - ＆gt;config-＆gt;销售电子邮件 - ＆GT;发票电子邮件。
2. 检查是否所有工作crons
