When I look at your corresponding screenshot, the Event node has status _ **"disconnected"** _:

When the node is disconnected, that is normally due to wrong ip/port/username/password. But of course there can also be a bug in the code. Because the whole (dis)connect recently has been rewritten for this [issue](https://github.com/bartbutenaers/node-red-contrib-onvif-nodes/issues/9), but it is not tested yet by the people that can reproduce the issue.

But I can imagine that a disconnected node results in errors like _"TypeError: Cannot read property 'device' of undefined"_. Of course the message should become user friendly...

Does this error appear when you inject a message via the _"start listening"_ button???

Ok thanks for confirming that!

I don't see any node status:

Is there also no status visible when you have injected an input message, to start the discovery?

I found also a bug in my discovery node, which I need to solve somehow (see [discussion](https://discourse.nodered.org/t/object-property-becomes-undefined/50647)).

Seems other people with such a camera had the same [issue](https://github.com/agsh/onvif/issues/76#issuecomment-315887373) with the library that I'm using ;-(
