"Call to a member function getItemById() on array" when viewing frontend posts

[Larke12]

Describe the bug After updating the composer package to 2.11.3 (from 2.11.0.1) the frontend blogs stopped loading, throwing the following error:

Error: Call to a member function getItemById() on array in .../vendor/magefan/module-blog/Model/UrlResolver.php:190

This appears to be due to the function \Magefan\Blog\Model\Post::getParentCategories no longer returning a collection, but an array. Reverting this function via an override to use the old code resolves this issue.

Preconditions:

• Magento Version: 2.4.6-p5
• Module Version: 2.11.3
• PHP Version 8.1

To Reproduce Steps to reproduce the behavior:

1. Go to blog post list on frontend
2. Click on any blog post
3. See error

Expected behavior The blog post loads without issue.

Actual behavior The blog post does not load at all and throws only an exception with stack trace.
