PHPStan fails for the current codebase

[hussainweb]

Description

PHPStan reports errors when run manually or during a CI run. I saw this first when working on #58 but then I reproduced this on the main branch as well. That is the reason I am creating a new issue and a PR.

Steps to reproduce

1. Make sure you are on the latest dependencies with composer update
2. Run composer dev:analyze:phpstan

Expected behavior

We should see a message from PHPStan saying [OK] No errors.

Screenshots or output

See output below or on one of the recent CI runs.

❯ composer dev:analyze:phpstan
> phpstan analyse --ansi
