Symfony2, Doctrine, fixtures, Array to string conversion - symfony

Question

I am working with my database already a month. Suddenly i started to get the error:
[Symfony\Component\Debug\Exception\ContextErrorException]
Notice: Array to string conversion
, when loading fixtures. Finally, i deleted all database, rerun migrations, left only 1 fixtures file (thus i commented our OrderedFIxturesInterface, and of course i cleared the cache, but the error remains).

Table contains varchar fields except of tinyint for boolean IsActive. There is only one tabel with name users.

Answer 1

The problem was with roles field, which i changed yesterday evening to the string instead of array. But i forget to remove initialization $roles = array();
/**
* #var string
*
* #ORM\Column(name="roles", type="string", nullable=true)
*/
private $roles; // it was $roles= array();
Thus if you see this error, search for keyword "array" in related files and check if assign variable is supposed to be equal to array, etc..
This is the fourth time when i have redone all project because of simple error. The conclusion is that better it to keep thinking where can be a mistake. On the other hand, when doctrine was not generating crud, reinstalling the project with different Symfony version helped.
private $roles; // = array();
