Weird: use of a button causes "Connection lost"

Is that line on the front in the file, or did you mess up the copy/paste. If you click the pencil icon next to the post you can correct it.

Did you uninstall the file function node before posting that, as suggested by @zenofmud? What does the startup log look like now?

As previously suggested it would probably be a good idea to update node red before giving up.

Latest dashboard requires at least nodejs 14. You are using v12. You will need to upgrade

@dceejay

Latest dashboard requires at least nodejs 14

Are you sure that is correct? When this question was first posted I checked Releases · node-red/node-red-dashboard · GitHub the last reference to nodejs is for version 3.0.4 which says "Set minimum requirement to be Node12 (in line with core)".
Also, package.json has

    "engines": {
        "node": ">=12"
    }

true... but it may be that one of the libraries has updated enough to break it. I guess they could try pinning back to a previous version of dashboard... but I think upgrading would be better longer term.

Certainly.

The original problem occurred on NR v2.1.4. zSince then the user installed NR v 3.02 on another Pi and the problems gone away.
