1. I’m trying to deploy a backend file using Express + typescript + prisma via Elastic beanstalk.
2. I tried various methods recommended in the official documentation.

I did a lot of searching and spent 4 days on it.

I think it might be related to package.json.

This is an error message that keeps occurring.

This is a GitHub link to the code file I am trying to distribute.

Here are the methods I tried and the link to the document.

1. Add the prisma CLI package to your dependencies instead of the devDependencies. (Making sure to run npm install afterward to update the package-lock.json).
2. Or install your devDependencies on AWS Elastic Beanstalk instances. To do this you must set the AWS Elastic Beanstalk NPM_USE_PRODUCTION environment property to false.

3.you need to create an .npmrc file in the root of your project and add the following configuration.
