Most likely you have a di.xml reference to an implementation of Magento\InventorySalesApi\Api\StockResolverInterface that is inside a module that is disabled.

Search your code base for Magento\InventorySalesApi\Api\StockResolverInterface in di.xml to find exactly which one it is and enable that module.

You could also do bin/magento module:status and enable your modules one by one until it starts to work.

I also see in your error message that the error comes from Amasty\Shopby, so it could be that the Amasty is referencing to a class that either is disabled or do not exist anymore, you could try updating the Amasty module.

  • Thankd for the pointer but cant find Magento\InventorySalesApi\Api\StockResolverInterface in the di.xml Commented Nov 15, 2020 at 13:24
  • Is there a way to rebuild the di.xml file from scratch? Commented Nov 15, 2020 at 16:59

Found the offending mod as mentioned in the error message uninstalled amasty shopby, compiled site and re-indexed and now working fine


I had this issue on one project where all Magento_Inventory* were disabled. When we upgraded the core, new Magento_Inventory* modules got enabled by default which caused the error.

By doing a quick search on etc/config.php, I quickly found and disabled all those new modules and the error was gone.


I'm using https://github.com/yireo/magento2-replace-all to replace some magento modules. The "amasty/shiprestriction" forced me to pick some modules out of the replace list:

    "magento/module-inventory-source-selection-api": "*",
    "magento/module-inventory-api": "*",
    "magento/module-inventory-configuration-api": "*",
    "magento/module-inventory-sales-api": "*",

After installing "amasty/xsearch" I got this error too, so i removed the following replace:

    "magento/module-inventory-sales": "*",

After that, the indexing process works again. The reason is, that now the following preference is available:

    <preference for="Magento\InventorySalesApi\Api\StockResolverInterface" type="Magento\InventorySales\Model\StockResolver"/>

The codeblock from "amasty/xsearch", which referenced the api-module:

<virtualType name="searchStockResolver" type="Amasty\Xsearch\Model\Di\Wrapper">
        <argument name="name" xsi:type="string">Magento\InventorySalesApi\Api\StockResolverInterface</argument>
