It becomes optional when I set `@ORM\Column(nullable=true)` but my column can't be null in db. > https://github.com/api-platform/api-platform/issues/872#issuecomment-455198847 I think another way would be with the new `input_class` you could create...

`@Attribute("graphql", type="array")` - `"array"` not very informative.
