I solved 502 bad gateway error in nodejs application deployment on elastic beanstalk

Problem

I was trying to deploy my Nodejs application in Elastic Beanstalk but I keep a 502 Bad Gateway error.

I checked the health causes

How I solved it

When uploading your code to the elastic beanstalk, it is expected to be zipped.

I zipped all my files excluding the node_modules and it worked perfectly.

Hope this helps someone in deploying your application to elastic beanstalk
