Hello,

I keep on receiving this error :

ERR! code EINVALIDTAGNAME

Node-red has been updated to the last version (1.2.6) and I am running Node.js v15.1.0 My OS is ubuntu 20.04

which version of npm are you running ? `npm -v` ... we have seen some weirdness with npm 7 ... We recommend Node.js 14 LTS rather than 15 at this point.

We fixed that weirdness in Node-RED 1.2.4. however, if you installed an extra module with npm 7 before you upgraded to 1.2.6 then your package file will already have been corrupted. So downgrading node isn't going to help fix that.

The fix is to edit `~/.node-red/package.json`, look under the dependency section for something like `"\"~\"3.10.4"` and change it to `"~3.10.4"`.
