Another issue:

We failed to locate the entry point for your program:

Here's what we think went wrong:
      * Your program looks like it has a build script associated with it ('DESTFOLDER=dist/lambda-layer/nodejs && mkdir -p ${DESTFOLDER} && cp package.json package-lock.json ${DESTFOLDER} && npm install --prefix ${DESTFOLDER} --production --ignore-scripts && rm ${DESTFOLDER}/package.json ${DESTFOLDER}/package-lock.json && nest build').

but it is built...

ls dist/app |wc -l
