@aligent-lturner I've updated the code with support php 8 , but looks like https://github.com/aligent/magento2-prerender/actions/runs/7578261074/job/20640572687?pr=6 coding standards check php 7.4 and failed.
Shall I readjust the code for PHP 7.4 ?

@anton-karunarathne-aligent you should be able to update the github action here (https://github.com/aligent/magento2-prerender/blob/1fb6078987616e8280db677dacbb2f33ad7e6723/.github/workflows/php.yml) to use the 8.1 version of the pipe

[aligent-lturner]

@anton-karunarathne-aligent you will also need to update composer.json to only support v8.1

[anton-karunarathne-aligent]

@aligent-lturner after I've updated the git hub action on https://github.com/aligent/magento2-prerender/blob/1fb6078987616e8280db677dacbb2f33ad7e6723/.github/workflows/php.yml pipe as 8.1 , I'm getting following error. Any idea to solving the issue.
