null exception after reading data

[Altaf-jg]

Hi,
I am getting the data sent by server followed by an exception.

Data sent from server:
message : {"User":763207291}

Exception:
Retry: 3000 - Error: System.ArgumentNullException: Value cannot be null.

The null exception is because the variable line is null at line# 127 in EventSourceReader.cs.

Any idea why it is null & how to handle this. I tried break if line variable is null, this disconnects the sever, doing continue goes into an infinite loop.

Regards,
Altaf
