Hi!
I`m currently facing a known problem, at least for me :)!
I need to find a way to use polymorphic input types when executing a mutation.
I found on Google that some people faces the same issue and one current proposed solution is to use an input object type with one field per "concrete class". This approach is very incomplete for me because you have to validate the request server side and the client is not sure about what is happening at the backend logic.
I hope that anyone can help me to find a best solution!
Thanks,
Patricio.
