Hi Andreas,

Upon investigating the issue I see the observed error seems to be related to a missing closing bracket of the @section scripts{...} that is present in the source code, but for some reason not displayed in the source and not passed to the REPL, thus causing the observed error. We will investigate that, but for the time being you can run the example in the REPL by removing the @section scripts{ from the code snippet:

@section scripts { //remove this line
    <!-- Load Pako ZLIB library to enable PDF compression -->
    <script src="@Url.Content("~/shared/pako.min.js")"></script>
    <script>
        // Send the dates for the newly creted/updated tasks as UTC strings
        function onUpdateCreate(e) {
            e.End = e.End.toISOString();
            e.Start = e.Start.toISOString();
        }
    </script>

Here is a runnable REPL if the example.

Regards,
Aleksandar
