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?
