I have the following activity definition: ```csharp [Function(nameof(FlakeyActivity))] public static void FlakeyActivity([ActivityTrigger] object _) { throw new ApplicationException("Kah-BOOOOM!!!"); } ``` Source-gen tried to produce the following: ```csharp public static Task<void> CallFlakeyActivityAsync(this TaskOrchestrationContext ctx, object _, TaskOptions? options = null) { return ctx.CallActivityAsync<void>("FlakeyActivity", _, options); } ``` Obviously, this didn't compile. It seems we need to handle this as a special-case.
