NodaTime types in GraphQL
License: MIT License
I'm fairly new to GraphQL.NET, so maybe I'm missing something. When I add a nullable NodaTime field such as LocalDate?
, I receive the following error:
The GraphQL type for field '<date field>' could not be derived implicitly from expression 'w => w.<date field>'.
It works fine for non-nullable fields.
Is there something I need to do to make this library work with nullable fields?
Update:
I've managed to get this code working:
Field(w => w.SomeDate, type: typeof(LocalDateGraphType))
However, the code below won't compile because "There is no implicit reference conversion from 'GraphQL.NodaTime.LocalDateGraphType' to 'GraphQL.Types.IGraphType'.":
Field(w => w.PlannedArrivalDate, type: typeof(NonNullGraphType<LocalDateGraphType>))
How do I create a non-nullable type?
Update again:
I suspect the problems are due to the reference to GraphQL being very out of date: this project references v2, but GraphQL has moved on to v7, and some of the AST code has changed.
