Sorry if the question could be stupid, but I don't know how to solve this.
I recently upgraded my OS to new Lubuntu version 20.04 and I lost my files.
I re-installed Node-RED and now I don't have 1.0.5, but 1.0.6 version.
My node-red was installed into /usr/local/lib/node_modules/node-red/ and the .nod-red folder into /home/USER.
Why now when I use a custom node, I get this error? Before these changes all worked perfectly.
EDIT: Also if I install mqtt globally, I get the same error.
