but based on the logs before this exception, the com.sample.model.AsyncPostgresSQLContext is Initialized and a connection to the postgres is establish.

Hope you can help me.

Thanks,

Hi,

I have the same problem but couldn't figure out the causing exception. Would you please explain more?
I even used TransientMemoryStorage but the result is the same.

Activate version: 1.7 - Scala version: 2.11.1

Amir
