QUESTION:

I installed your latest version 1.3.4 on our site Magento 2.3.0 and I got the error below when deploying:

Fatal error 'Magento\Customer\Adminhtml\Address\Save' not found in xxx/xxx/app/code/Bss/CustomerAtrributes/Plugin/customer/controller/Adminhtml/Address/Save.php on line 20

Please send us the fix?

ANSWER:

To fix this error, please edit the files as below:

+ app/code/Bss/CustomerAttributes/Plugin/Customer/Controller/Adminhtml/Address/ { Save.php → Save.php__ }

File renamed but contents unchanged.

+ app/code/Bss/CustomerAttributes/Plugin/Integration/Model/Customer/DataProvider.php

Please download the files attached below to override the current files on your site.
