Error when using aggregates in grid when hosted in azure app service

[Brian]

I am using the 2018.1.221 Kendo UI for .Net Core.  It is a ASP MVC Core app using .net core 2.

This is a grid with Ajax source - the part having issues is here:

            .DataSource(dataSource => dataSource
                .Ajax()
                .Aggregates(a =>
                {
                    a.Add(l => l.Balance).Sum();
                })
                .Read(read => read.Action("Balances_Read", "Balances").Data("getAccountType"))
                .PageSize(250)
            )

This works fine on my development machine (and on a different site hosted on Azure) but on this particular app service I get this exception.  The exception goes away if I remove the aggregates code.  Here is the stack trace upstream from my call:

 

System.Exception: Unable to build typeDynamicClass3

   at Bryt.Client.Web.Controllers.BalancesController.Balances_Read(DataSourceRequest request, Int32 accountType) in C:\DataDrive\Working\Bryt\Bryt.Client.Web\Controllers\BalancesController.cs:line 65

 

Again, oddly, this is isolated to running on Azure.

Thanks,

Brian
