STEP-3 Accessing Magento 2 Controller, Bypassing ScandiPWA frontend

1. Add ScandiPWA_Route717 as a sequence to your [MODULE]/module.xml

app/code/ScandiPWA/Version/etc/module.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
   <module name="ScandiPWA_Version">
       <sequence>
           <module name="ScandiPWA_Route717" />
       </sequence>
   </module>
</config>

2. Create di.xml file in [MODULE]/etc folder

app/code/ScandiPWA/Version/etc/di.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <virtualType name="ScandiPWA\Router\Controller\ConfigurableRouter" type="ScandiPWA\Router\Controller\Router">
       <arguments>
           <argument name="ignoredURLs" xsi:type="array">
               <item name="getscandipwaversion" xsi:type="string">^/scandipwa/version.*</item>
           </argument>
       </arguments>
   </virtualType>
</config>
