Application failed unexpectedly Could not connect to amqp - wolkenkit

Question

I'm using wolkenkit 1.2.0,
I'm starting wolkenkit this way:
wolkenkit start --shared-key 123456 --verbose
I'm sending commands and I can see them in the logs, but I'm not receiving events. Could it be related to the following error I'm seeing in the logs all the time:
Application failed unexpectedly. (fatal)

}
}
I've tried upgrading to 1.2.1 with no help.
I've deleted all the containers and started from the top. Still not working.
Edit:
Full Log of the basic chat app:

Answer 1

As discussed in the comments, I think that this problem is specific to your application, not to wolkenkit in general.
In my opinion I think that you need to figure out which command or event causes your application to not work properly. Unfortunately, I can't help with that too much, without having a closer look at the application's code.
I'm very sorry that I don't have a better answer for you.
However, I hope this at least helps to point you into the right direction.
