KeyStat json deserialization fails on null nextdividentdate value

[kewur]

Looks like IEX changed something on their API again making the KeyStat deserialzier fail on null DateTime values

Is this still an issue for you? I added a test for TSLA and it passes for me.

really? surprised it does. it's possible there is some configuration in my code that might be effecting it then on my environment. I did end up implementing a new call with restsharp though so I'm not using this class anymore, we can close this issue, maybe it was my setup. I even created a unit test by checking out the current IEXSharp HEAD and that was failing as well with the same error.
