Getting NullReferenceException from Sitelet.InferWithCustomErrors

[lierdakil]

Here's a relevant portion of the backtrace:

[NullReferenceException: object reference not set to an instance of an object.]
   WebSharper.Sitelets.ServerInferredOperators.IWithCustomErrors(Type typ, InferredRouter item) +164
   WebSharper.Sitelets.Router.IInferWithCustomErrors() +57
   WebSharper.Sitelets.SiteletModule.InferWithCustomErrors(FSharpFunc`2 handle) +81

Let me know if I can help debug this.

Thanks for the report!

As a quick workaround, try Sitelet.Infer<ParseRequestResult<T>> instead, where T is your endpoint type.
This should be equivalent, only there is a bug currently in InferWithCustomErrors.

[Jand42]

Ok, sorry, not entirely equivalent, because InferWithCustomErrors also fixes up the Context object to create links for type T instead of ParseRequestResult<T>.

You can do this too with let ctx = (Context.Map ParseRequestResult.Success ctx).

Thanks for quick response and for suggesting a workaround!
