I have a Nest.js (Node.js) application, and I want to deploy it on ElasticBeanstalk (Node 16 version, AL2 5.5.0).
My deployment keeps failing, and I found the error in eb-engine.log.

I think the error occurs when installing npm packages in production mode, but I'm really wondering why this happens. I executed npm --production install in my local computer, the installing was successful with the exactly same versions of node & npm. (Node 16.14.0, npm 8.3.1 - AL2 5.5.0 latest for now).
I want to know why this happens and how to debug more details (why npm install failed in the elastic beanstalk environment).
I had the same issue, and the only way I could find to solve it was to increase the size of the instance running the application. In order for it to work, I had to use t2.medium.
You can also try increasing the swap for the EC2 instance running your app, but in my experience this made the deployment process take too long and sometimes fail. (See this answer if you want to try that approach)
