Error returning multiples values in a function using nethereum

Using Nethereum and metamaks for unity, a method of the smart contract returns multiples values (string and uint256), but Im receiving this error:
ArgumentException: Unknown type: String

Nethereum.ABI.ABIType.CreateABIType (System.String typeName) (at <0d1075de7bdd41818dd704e77f9150ca>:0)

I have tried multiple solutions related to this documentation Multiple output parameters and function DTOs from Netehreum websoite but this doesnt works, something know what can be happening?
thanks

Hi @nbmtabizz let me check internally have you tried reaching out Nethereum community: Nethereum if the discord link expires check for new one under discord here: https://playground.nethereum.com/

By the way, there are no plans to integrate sdk with nethereum, SDK can do pretty much the same things without using Nethereum please try: Interact with smart contracts in Unity | MetaMask developer documentation
