Unable to insert/update array with DBAL functions

[k0d3r1s]

If database table column has type array (deprecated but possible type) it is impossible to insert/update array into this field.
If database table column has type json, then only way to insert/update data in database, is to switch entity variable type from array to mixed and set data using valid json string instead of array

---

old:

#[ORM\Column(type: 'json', nullable: true)]
private ?array $data = [];

new:

#[ORM\Column(type: 'json', nullable: true)]
private mixed $data = [];

Edit: null|array|string version seems to break entity mapper, need to use mixed instead
