Debug nodes are not working properly

General
1

There is no debug messages displayed for debug nodes.

And I always got below error after I triggered the flows with debug nodes in use.

You haven't provided much information to allow someone to help you.

  1. what platform and OS are you running NR on?
  2. what version of Node-RED are you using?
  3. What version of Node.js?
  4. Have you ever seen a debug message in the sidebar?
  • if so what changed?
  1. Are the debug nodes active?

If none of this helps, please provide your flow but read this thread first.

Also, where is the machine you've installed it on (LAN or cloud) and where are you trying to access it from (same LAN or somewhere else)

Hi zenofmud.
Here are the questions for your questions:

  1. Our NR is running on IBM public cloud foundry .
  2. The version of Node-red is 0.8.0 currently.
  3. The version of Node.js is 6.x currently.
    Here is the NR setting file:

  4. The debug message was displaying normal previously until about last month and nothing changed.
    (the debug message were not working on all my 6 NR)
  5. The debug nodes are activated.

Hi cymplecy,
The NR are installed on cloud and I am accessing it from my laptop.

Thanks very much for your reply and sorry for my late response. I was on vacation last week.

It looks like whatever you have behind your inject node let the flow & Node-RED crash (see “lost connection” message). Likely Node-RED is running as a service and restarts immediately but you will never see something on your debug node.
Perhaps you should take a look on your console or log-file for error messages (if possible when running Node-RED in a cloud)
