DSL - Datetime argument serialization failing

[FelixNuvolar]

Hello,
Using GQL 2.0.0, and trying to pass datetime arguments in mutation requests, we realised that the result value of the DSL serialisation was none for such fields.

It seems related to the way Scalar types are build, passing _none as a serializer method (/lib/python3.9/site-packages/graphql/utils/build_client_schema.py:146)

Are we missing something or is this a bug ? For now the only solution we found is to monkey patch the args() method of the DSLField class to implement custom serialization.

Best regards,
Felix

Sorry, custom scalars are not yet supported.
