[已解决]自定义custom_address属性无法保存到客户地址簿

給custom_address新增了五个属性，并且在checkout界面显示了， 现在这五个属性可以保存到quote_address和sale_order_address, 但是这五个自定义属性无法保存到addres_book, 如果从后台编辑客户地址，可以保存，但是从checkout页面传值过去，无法保存

extension_attributes.xml

<extension_attributes for="MagentoQuoteApiDataAddressInterface">

    <attribute code="code_destination" type="string"/>    
    <attribute code="pec" type="string"/>    
    <attribute code="need_invoice" type="string"/>

这是前台的传值
