Symfony-Catchable Fatal Error: Argument 1 passed t

Question

I am getting this error while trying to load my page(Symfony 3.3):

Catchable Fatal Error: Argument 1 passed to Doctrine\Common\Collections\ArrayCollection::__construct() must be of the type array, object given`.

I have looked at many websites but none of them was able to solve my problem.
Below is an example of my entities:

Answer 1

As I expected it was something very small that was causing it. In my controller I was using setConfig to add data but instead I should have used the addConfig automatically generated by Doctrine.
