Running selenium test from GIT with Jenkins on remote Selenium grid - selenium

Question

I am trying to run selenium test from git with Jenkins job on selenium grid in docker.
Job is supposed to get .js which is holding test and connection to grid. This file should be executed with build in jenkins. Since I am using nodeJS with selenium, I need Jenkins to get all requested npm packages.
In Jenkins, I downloaded nodeJS plugin and in Global Tool Configuration I filled selenium-webdriver#4.1.2 in column Global npm packages to install (nodeJS version I chose 18.1.0)
Job successfully get git repo. In Build I have simple command node login.js.
Unfortunately when I am trying to build that job, I am still getting MODULE NOT FOUND for selenium-webdriver.
In log from build there is different module error, because I tried to add node_modules/selenium-wedriver directly to repo. But I guess that this is not the right way.
Anyone could point me the right direction please?

Build step 'Execute shell' marked build as failure

Answer 1

So I get this working.
Only thing I did was add another Build step > Execute shell - npm install before step executing node login.js.
So what it is doing (I suppose) is that npm install will try to install packages from package.json every single build.
Now I am going to find out, how to cache this :)
