HoloLens OCR issue


I am working on the OCR for the HoloLens to leverage this feature in our application.

Used this https://github.com/TakahiroMiyaura/HoloOcrSamples project as a reference.
I am getting this error while scanning...
(Already done all necessary Capabilities check i.e. 'webcam' and 'microphone' for application)

Exception thrown: 'System.ArgumentNullException' in System.Linq.dll
ArgumentNullException: Value cannot be null.
Parameter name: source
at System.Linq.Enumerable.OfType[TResult](IEnumerable source)
at UWPBridgeService.GetServiceT
at CameraScript.Update()
at CameraScript.$Invoke9(Int64 instance, Int64* args)
at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method)
(Filename: Line: 0)

let me know if anyone has solutions on this or worked on this.
