git error while loading shared libraries on nodejs10.x

[mxfactorial]

steps

1. create bucket

   aws s3api create-bucket \
     --bucket unique-bucket-random-123 \
     --region us-east-1

2. save index.js

   const util = require('util')
   const exec = util.promisify(require('child_process').exec)
   
   const REPO = 'https://github.com/gkrizek/bash-lambda-layer.git'
   const TMP_DIR = '/tmp/bash-lambda-layer/examples'
   
   exports.handler = async event => {
     await exec(`cd /tmp && git clone --depth 1 --single-branch --branch master ${REPO}`)
     let lsOutput = await exec(`ls ${TMP_DIR}`)
     if (lsOutput.errorMessage) { return lsOutput.errorMessage }
   }

3. zip index.js

   zip src.zip index.js

4. put zip in s3

   aws s3api put-object \
       --bucket=unique-bucket-random-123 \
       --key=src.zip \
       --body=src.zip

5. save template.yaml referencing bash layer in nodejs10.x lambda

   AWSTemplateFormatVersion: "2010-09-09"
   Description: "bash8 layer bug on nodejs10.x"
   Parameters:
     BucketName:
       Type: String
   Resources:
     SharedLibraryBugRepoLambda:
       Type: AWS::Lambda::Function
       Properties:
         FunctionName: bash8-layer-bug-on-nodejs10
         Description: "repro libcurl.so.4: cannot open shared object file"
         Handler: index.handler
         Role: !GetAtt SharedLibraryBugRepoLambdaRole.Arn
         Runtime: nodejs10.x
         Timeout: 10
         Layers:
           - !Sub "arn:aws:lambda:${AWS::Region}:744348701589:layer:bash:8"
         Code:
           S3Bucket: !Sub ${BucketName}
           S3Key: src.zip
     SharedLibraryBugRepoLambdaRole:
       Type: AWS::IAM::Role
       Properties:
         AssumeRolePolicyDocument:
           Version: '2012-10-17'
           Statement:
             - Effect: Allow
               Principal:
                 Service:
                 - lambda.amazonaws.com
               Action:
               - 'sts:AssumeRole'
         Path: /
         Policies:
           - PolicyName: SharedLibraryBugRepoLambdaLoggingPolicy
             PolicyDocument:
               Version: '2012-10-17'
               Statement:
                 - Effect: Allow
                   Action:
                     - 'logs:CreateLogGroup'
                     - 'logs:CreateLogStream'
                     - 'logs:PutLogEvents'
                   Resource: 'arn:aws:logs:*:*:*'
     SharedLibraryBugRepoLambdaLogGroup:
       Type: AWS::Logs::LogGroup
       DependsOn:
         - SharedLibraryBugRepoLambda
       Properties:
         RetentionInDays: 90
         LogGroupName: !Sub /aws/lambda/${SharedLibraryBugRepoLambda}

6. provision template

   aws cloudformation create-stack \
     --capabilities CAPABILITY_NAMED_IAM \
     --stack-name bash8-layer-bug-on-nodejs10x \
     --template-body file://$(pwd)/template.yaml \
     --parameters ParameterKey=BucketName,ParameterValue=unique-bucket-random-123

7. invoke lambda

   aws lambda invoke \
     --invocation-type RequestResponse \
     --function-name bash8-layer-bug-on-nodejs10 \
     --payload '{}' \
     invoke.log \
     && cat invoke.log

observed

*teardown:

1. aws cloudformation delete-stack --stack-name bash8-layer-bug-on-nodejs10x
2. aws s3api delete-object --bucket unique-bucket-random-123 --key src.zip
3. aws s3api delete-bucket --bucket unique-bucket-random-123

Sorry for the late response. You can't use this layer with any runtime other than provided. When you use runtime nodejs10.x it invoke the node.js bootstrap file, not this one. And I'm sure there's other differences in the environment that I don't know about.
