Can anyone suggest something here?

What does your Jenkinsfile look like, to start with. And do the variables it references actually exist in Jenkins?

I am just following the lecture of Jenkins Pipelines. I have declared variables for mongo db uri, uname and password.

tools {
nodejs ‘Nodejs-gb-23.8.0’

    MONGO_URI = "mongodb+srv://supercluster.d83jj.mongodb.net/superData"

What were the values of the credentails you used? They are all case dependent, so if you get the case wrong, it won’t work. The code itself looks right to me. Also: what was the exact error you see in the Jenkins logs?

Hi Rob,

Error has been resolved, after changing the PORT number used in the application. thanks for your support.
