Possibly continues happily.

Just a note that it seems to occur most often when editing binding information.

I'm seeing this happen more and more on certain hosts now.

@justparking Just to note, this seems to occur when you have a node saved in a binding, but no event or action specified.

[justparking]

There is data that was previously santised before handing it over to the nodel server in the previous frontend version that is now no longer sanitised.

A workaround for the moment is to restart the node, OR have make sure either:

1. both node name AND action/event name are cleared
2. both node name and action/event name have data present, even dummy data if necessary.

Fix in progress...
