Node Status - queries about text is null

General
1

Is it normal in case of 2, Node Status to block the whole flow ?
Basically, if 'text' has the value null, the execution of the flow stops at that node.

It doesn't block the flow - if you change the Debug node to also long to the console, you'll see the message arrives.

But it does appear that the editor doesn't handle a payload will a null value - you get this error in the editor:

Which is odd - this definitely used to work.

What version of Node-RED are you using?

3

Same result in :

  • Node Red 1.0.5 and 1.0.6
  • NodeJS 10 and 12 (all version of 12)
  • Windows 7, 10 and Ubuntu
4

Also, Debug 3 is ... unreachable. You're right, he appears in the console
