Parsing Logs results in an error: Invalid cast from 'Int64' to 'DateTime'.

[bjarketrux]

Hi,
I'm getting an error trying to inspect Meta Logs from a gererated report (using the .NET client).

I'm accessing the logs as such:

var report = await reportingService.RenderAsync(request);
var logs = report.Meta.Logs.ToList();

Doing so results in the following error (Windows 64bit, Asp.NET Core 3.1 Console application):

Invalid cast from 'Int64' to 'DateTime'.
   at System.Int64.System.IConvertible.ToDateTime(IFormatProvider provider)
   at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider)
   at Newtonsoft.Json.Linq.Extensions.Convert[T,U](T token)
   at Newtonsoft.Json.Linq.Extensions.Value[T,U](IEnumerable`1 value)
   at Newtonsoft.Json.Linq.Extensions.Value[U](IEnumerable`1 value)
   at jsreport.Shared.SerializerHelper.<>c.<ParseReportMeta>b__0_0(JToken s)

I have traced the error to this Repository in ParseReportMeta:

Timestamp = s["timestamp"].Value<DateTime>()

In context:

public static ReportMeta ParseReportMeta(IDictionary<string, string> meta)
{
    IEnumerable<LogEntry> logs = null;

    if (meta.MetaValue("debugLogs") != null)
    {
        var joLogs = JArray.Parse(meta.MetaValue("debugLogs"));
        logs = joLogs.Select(s => new LogEntry()
        {
            Message = s["message"].Value<string>(),
            Level = (LogEntryLevel)Enum.Parse(typeof(LogEntryLevel), s["level"].Value<string>(), true),
            Timestamp = s["timestamp"].Value<DateTime>()
        });
    }

    ...
}

I extracted the parsing logic into my application and changed the line to the following which seemingly works:

Timestamp = DateTimeOffset.FromUnixTimeMilliseconds(s["timestamp"].Value<long>()).UtcDateTime

Is it a bug or perhaps something with my setup?
