@aadarshjain-dev any idea why is PHPSTAN reporting issues in file

that doesn't exist in this branch but exists in the staging branch? I don't see how it would be possible with my limited knowledge of Github Action config files.

EDIT: It looks like it's the default behavior and there are good reasons for it: https://github.com/actions/checkout?tab=readme-ov-file#checkout-pull-request-head-commit-instead-of-merge-commit

@escopecz so is this particular issue resolved/addressed by you?

[escopecz]

Yes, it's resolved. Thanks for asking. I'm trying to make PHPSTAN and PHPUNIT work before we merge this.

Great!!
Also when PHPSTAN and PHPUNIT are fixed, we can remove the commented steps to make the file clean (if not being used further)

[escopecz]

Will do!
