How to fix the incompatible issue with M2.2.x?

Issue:

I purchased your extension "Simple Details on Configurable Product", but when I install version 1.2.9 on M2.2.0, I get the following error:

PHP Fatal error:  Interface 'Magento\Framework\App\Action\HttpPostActionInterface' not found

in /app/code/Bss/Simpledetailconfigurable/Controller/Ajax/Product/Post.php on line 25

Could you please check and fix it?

Solution:

The current version 1.2.9 is not compatible with M2.2.x at this time so it caused the issue above.

To solve it, please edit these files as below:

app/code/Bss/Simpledetailconfigurable/Controller/Ajax/Product/ListAction.php

app/code/Bss/Simpledetailconfigurable/Controller/Ajax/Product/Post.php

app/code/Bss/Simpledetailconfigurable/Model/Product/Type/Configurable.php

app/code/Bss/Simpledetailconfigurable/view/frontend/web/js/price-box.js

app/code/Bss/Simpledetailconfigurable/view/frontend/web/js/price-option-date-mixin.js
