node%20error

What version of node.js are you using? (node -v)

How did you install node-red?

installed it with this script bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered)

v10.16.3

Is it possible that it is the browser i am using? Explorer from windows 2012

When you restart Node-RED can you copy all the messages to here? (moved to #general as not about creating nodes)
