'Call to a member function get() on string' while browsing articles by TAG

[cloggg]

Some of my articles are tagged.
I also have a menu, which contains of items: 'Tags » Compact list of tagged items', where each item shows articles tagged with different tag
In majority, all items display correct results, however I cannot browse at least one specific tag list.
I got 'Call to a member function get() on string' error
I saw that there were some fixes of such problem done in version 3.9, but they did not work in my case (I had the same issues in 3.8.x, but decided to wait for 3.9)

I am able to provide more details, however I need to know what to look for.

Please let me know if you need additional information
Bests,

This solved the issue - thank you!
I will start using tags and report if I find any problem.
For the moment the solution looks OK ;)
