I am using node-red version 2.2.2 and node.js version 12.22.8. This instance was deployed in rancher kubernetes management platform. When I use nodered v2.2.2 inject node and debug nodes are enabled but debug outputs are not showing in the the panel but I get successfully injected message. I also tried upgrading to nodered version 3.0.2 In that inject nodes and debug nodes cannot be enabled. What can be the reason for this any fix?, I tried npm update but it didn't fix the issue.

With node-red 3.0.2 start node red in a command window and post the startup log here.

it is likely you have an issue in your flows or a contrib node preventing the flows from starting on the server.

the second common reason is that websockets are blocked.

Check the browsers dev tools -\> network tab for any rad requests.

And as @Colin said - post your startup log.

And one additional question - where/how are you running node-red - docker? nas? rasp pi? windows? etc etc

Please post the start of the log up to the error. Pasting it in is the correct way to do it.  
You didn't answer all of @Steve-Mcl's questions - in particular whether it is a docker install.

The node showing the error has not installed correctly, so I suggest you try installing that again.

As you can see, the install of nodes is messed up.  
I don't know anything about Rancher, but if this were a normal install I would recommend deleting the node\_modules folder, which in your system appears to be /data/node-modules, then, in a command window, going into /data and running  
`npm install`  
which should re-install all the required nodes. Watch for errors with this obviously.

As for the sockets connection problem then it appears that the browser cannot open a web socket connection to the server. That may be a Rancher problem.

As rancher is container based (think docker) your images will need the tools necessary for compiling certain nodes that have a build step (like serial port etc)

Covered many times on the forum. Search "[docker build serial](https://discourse.nodered.org/search?context=topic&context_id=80176&q=docker%20build%20serial&skip_context=true)"
