Magento:无效的 block 类型

Question

我得到以下异常(exception)情况。不幸的是，我真的无法在互联网上找到解决方案。

由于这些异常刚刚出现，当我激活 OneStepCheckout 扩展程序时，我认为这是这个问题。

商店里一切正常(据我测试)，但我认为应该始终注意异常(exception)情况。

我已经尝试过对 Mage_Braintree_* 进行文件搜索，但没有找到任何内容。

有什么建议吗？

编辑: 感谢 Prakash Thapa。我在 app/design/frontend/base/default/layout/lotusbreath/onestepcheckout.xml 中找到了一个 braintree 部分

<!-- For braintree -->
<lotusbreath_onestepcheckout_index_index>
    <reference name="head">
        <action method="addJs" ifconfig="payment/braintree/active"><file>braintree/braintree-1.3.4.js</file></action>
        <action method="addCss" ifconfig="payment/braintree/active"><stylesheet>braintree/css/braintree.css</stylesheet></action>
    </reference>
    <reference name="before_body_end">
        <block type="braintree_payments/datajs" ifconfig="payment/braintree/active" name="braintree_payments_data_js" template="lotusbreath/onestepcheckout/braintree/data_js.phtml" />
        <block type="braintree_payments/form" ifconfig="payment/braintree/active" name="payment.form.braintree" template="lotusbreath/onestepcheckout/braintree/review_js.phtml">
            <action method="setMethodInfo"></action>
        </block>
    </reference>
</lotusbreath_onestepcheckout_index_index>

由于我没有使用任何 braintree 支付扩展，我应该删除这部分还是应该如何处理？

就目前而言，似乎只是删除(或注释掉)该部分效果很好。

此错误是由于布局 xml 中的无效 block 类型而发生的，例如

 <reference name="....">
        <block type=".." />
</reference>

尝试在 app/design/frontend/base/default/layout/EXTENSION_LAYOUT.xml 中找到问题设计布局 EXTENSION_LAYOUT.xml 可以是 braintree.xml 之类的任何东西。
