Issue:


We installed the extension successfully on M2.2.11 CE but on catalog price reindex we got an error 

PHP Fatal error:  Uncaught Error: Call to a member function registerTags() on null in /vendor/magento/module-catalog/Model/Indexer/Product/Price.php:80 


Solution:


The root of the issue is that version 2.2.1 for M2.2.6-2.3.0 is not compatible with M2.2.11.

To solve it, we have fixed file 

Bss\MultiStoreViewPricingPriceIndexer\Model\Indexer\Product\Price.php

Please apply the fix on the site.
