serialize() can not return null, so I'm getting GRAPHQL error {"errors":[{"message":"Expected JsonType.serialize(\"null\") to return non-nullable value, returned: null" error where JsonType is my customized scalar.
I know graphql-scalars package includes a JSON scalar type, but I'm using my custom one where serialize() can parse from a Buffer or string. It used to work but in graphql 16 I can not return null in serialize() after this change.
I'm wondering what's the recommended way to handle it in this case, if I use a wrapper all schema would need to change due to the nesting.
