1) I created Question entity with field Tags of simple_array type:

 /**
 * @ORMColumn(type="simple_array", nullable=true)
 */
 private $Tags = ;

 public function getTags(): ?array

 return $this->Tags;


public function setTags(?array $Tags): self

 $this->Tags = $Tags;

 return $this;

2) When I want to create a Question object and initialize Tags field like that:

 $question = new Question();
 $question
 ->setTags( array("1","2","3"));

then Symfony throws an error:

Array to string conversion

3) My question: Why is Symfony throwing the error and how can I fix it?

Is wrong typing cause of it?
