Nested deployment of AWS Lambda funtions with Jenkins - jenkins

Question

I am learning how to deploy AWS Lambda functions from Jenkins.
I have following forlder structure:
src -> favorites -> findAll -> index.js
src -> favorites -> insert -> index.js
src -> movies -> findAll -> index.js
src -> movies -> findOne -> index.js
Essentially 4x functions.
Here's part of Jenkinsfile:
def functions = ['MoviesStoreListMovies', 'MoviesStoreSearchMovie', MoviesStoreViewFavorites', 'MoviesStoreAddToFavorites']
stage('Build'){
sh """
docker build -t ${imageName} .
containerName=\$(docker run -d ${imageName})
docker cp \$containerName:/app/node_modules node_modules
docker rm -f \$containerName
zip -r ${commitID()}.zip node_modules src
"""
}
stage('Push'){
functions.each { function ->
sh "aws s3 cp ${commitID()}.zip s3://${bucket}/${function}/"
}
At the end I expect to have 4x AWS S3 buckets with same .zip content in it (i.e. all 4 same folders/functions present in each bucket).
Here now my issue. The build stage.
stage('Deploy'){
functions.each {
function ->
sh "aws lambda update-function-code --function-name ${function} --s3-bucket
${bucket} --s3-key ${function}/${commitID()}.zip --region ${region}"
}
}
Since the zip has same content, how can be that the 4 functions are deployed as exactly 4 functions? Again, each of the 4x .zip file contains in turn the same 4x folders/functions. So I would expect 4x4=16 functions eventually.
What am I missing?

Maybe my mistake. I missed to say that Lambda functions get created with Terraform first. And indeed Terraform creates handlers pointing to the right src paths:
module "MoviesStoreListMovies" {
source = "./modules/function"
name = "MoviesStoreListMovies"
handler = "src/movies/findAll/index.handler"
runtime = "nodejs12.x"
environment = {
TABLE_NAME = aws_dynamodb_table.movies.id
}
}
module "MoviesStoreSearchMovie" {
source = "./modules/function"
name = "MoviesStoreSearchMovie"
handler = "src/movies/findOne/index.handler"
runtime = "nodejs12.x"
environment = {
TABLE_NAME = aws_dynamodb_table.movies.id
}
}
module "MoviesStoreViewFavorites" {
source = "./modules/function"
name = "MoviesStoreViewFavorites"
handler = "src/favorites/findAll/index.handler"
runtime = "nodejs12.x"
environment = {
TABLE_NAME = aws_dynamodb_table.favorites.id
}
}
module "MoviesStoreAddToFavorites" {
source = "./modules/function"
name = "MoviesStoreAddToFavorites"
handler = "src/favorites/insert/index.handler"
runtime = "nodejs12.x"
environment = {
TABLE_NAME = aws_dynamodb_table.favorites.id
}
}
