JSON AggregateException when updating lights

[logicallysynced]

Hi there,

I seem to be getting this exception every few seconds when updating my lights (Hue Play). I'm just using the example code for now, and they do update correctly if I ignore the exception, but it would be good to find out the reason:

Color color = dataSet[0].color;
var rgbColorHue = new HueApi.ColorConverters.RGBColor(color.R, color.G, color.B);

// Create the light update command
var req = new UpdateLight()
    .TurnOn()
    .SetColor(rgbColorHue);
    
var result = _client.UpdateLightAsync(_light.Id, req).Result;

I'm fairly confident the error isn't coming from my codebase:

System.AggregateException
HResult=0x80131500
Message=One or more errors occurred. ('<' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0.)
Source=System.Private.CoreLib
StackTrace:

This exception was originally thrown at this call stack:
[External Code]

Inner Exception 1:
JsonException: '<' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0.

Inner Exception 2:
JsonReaderException: '<' is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.

Unable to reproduce this. Can you check what data your bridge returns by using a tool like Telerik Fiddler? It might return something else than json.
Maybe you're sending too many requests and it's better to use the Entertainment API?
