add-layer-to-lambda-

• upload zip package from mac to lambda, seems works

mkdir -p $$/python/lib/python3.11/site-packages
pip install flatten_json -t $$/python/lib/python3.11/site-packages
cd $$
zip -r package.zip ./python

• push layer version
  

  aws lambda publish-layer-version --layer-name layer_flatten_json --description "flatten_json" --zip-file fileb://package.zip --compatible-runtimes python3.8
  layer_arn=$(aws lambda list-layer-versions --layer-name layer_flatten_json \
  --query 'LayerVersions[0].LayerVersionArn' --output text)
  
  aws lambda update-function-configuration --function-name ${lambda_name} \
  --layers ${layer_arn}
