Can not find new node under palette

On last Friday, I created a node named '@mingxingzhang/node-red-contrib-tcp-request2' , published it on '@mingxingzhang/node-red-contrib-tcp-request2 - npm' and added it to ''. However, today I still cannot find it under the palette. After some searching, I find 'Actions · node-red/flow-library · GitHub' appears to have stopped updating. Could someone help me resolve this?

I don't know if this is a factor, but I do notice that the 'Node.js Version' is missing

THX, I'll try it later. Currently,npmjs login service Unavailable.
