Are you running node-red as root? That really is not a good idea, though I don't know whether that would cause the problem you are seeing.  
Did you install node-red using the recommended script from the docs? That would ensure you have a consistent set of tools.

i don't believe that the "root running" cause the problem, on another raspi node-red is running as root as well and on this raspi i don't get any errors.

I have installed node-red using the script from the docs.

The node requires an old version of the serialport module (6.2.2) which will not build on your system (nor on mine). My guess is that is too old for version 12 of nodejs.  
You could try reverting to nodejs 10 or 8, and if it works then raise an issue against the node. It is possible that it just needs its package.json hacked to allow it use the latest version of the serialport module.

Now I have changed the nodejs version to 10.20.1 and it works.

Thank you for your help

In that case add an issue to the node's github page, which is linked from the npmjs page. Then hopefully the author will fix it.
