Thingwatcher FAILED after training phase

Hi,

I try to test the anomaly detection. First I try it with a simple service which generates data. This Fails after a short time of "Training". Than I try it with the simulator of the tutorial (https://developer.thingworx.com/resources/guides/anomaly-detection-how-guide/training-anomaly-alerts). Same problem. The application logs displays:

I have no idea what is wrong.

I use ThingWorx 8.2.2-b167 and i thing thingwatcher 8.2.0 (but I'm not sure).
