aws-sam-cli: Sam Build Failed: NodejsNpmBuilder:NpmPack

After trying a SAM project using python, I suddenly need to create a package.json file for each lambda function.

Otherwise, I will get an error:

Build Failed
Error: NodejsNpmBuilder:NpmPack - NPM Failed: npm ERR! code ENOLOCAL

I don’t need any node_modules for my lambda function, so I would like not to include it in my folder.

For each function, this script will run.

Running NodejsNpmBuilder:NpmPack
Running NodejsNpmBuilder:CopyNpmrc
Running NodejsNpmBuilder:CopySource
Running NodejsNpmBuilder:NpmInstall
Running NodejsNpmBuilder:CleanUpNpmrc
