isNullable in OpenApiSchemaProperty not working

[marcdebus]

I defined a property for a datetime value in the entity as nullable, but it didn't work:

#[OpenApiSchemaProperty(name: 'deleted', type: 'string', format: 'date-time', isNullable: true, isReadOnly: true)]
class MyEntity extends Entity {

..

Generated output in swagger.json:

"deleted": {
                        "type": "string",
                        "format": "date-time",
                        "readOnly": true
                    }

Swagger Bake Version 2.5.9
