  Sample SAM Template using Application Auto Scaling + Provisioned Concurrency

Globals:
  Function:
    Timeout: 30

Resources:

  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: HelloWorldFunction
      Handler: helloworld.App::handleRequest
      Runtime: java11
      MemorySize: 1024
      AutoPublishAlias: live
      DeploymentPreference:
        Type: AllAtOnce # Or Canary10Percent5Minutes, Linear10PercentEvery1Minute, ...
      ProvisionedConcurrencyConfig:
        ProvisionedConcurrentExecutions: 1
      Environment:
        Variables:
          ENVIRONMENT: test
      Events:
        HelloWorld:
          Type: HttpApi # Using the new HTTP API here

  MyScalableTarget:
    Type: AWS::ApplicationAutoScaling::ScalableTarget
    Properties:
      MaxCapacity: 100
      MinCapacity: 1
      ResourceId: !Sub function:${MyFunction}:live # You need to specify an alis or version here
      RoleARN: !Sub arn:aws:iam::${AWS::AccountId}:role/aws-service-role/lambda.application-autoscaling.amazonaws.com/AWSServiceRoleForApplicationAutoScaling_LambdaConcurrency
      ScalableDimension: lambda:function:ProvisionedConcurrency
      ServiceNamespace: lambda
    DependsOn: MyFunctionAliaslive # This is your function logical ID + "Alias" + what you use for AutoPublishAlias

  MyTargetTrackingScalingPolicy:
    Type: AWS::ApplicationAutoScaling::ScalingPolicy
    Properties:
      PolicyName: utilization
      PolicyType: TargetTrackingScaling
      ScalingTargetId: !Ref MyScalableTarget
      TargetTrackingScalingPolicyConfiguration:
        TargetValue: 0.70 # Any value between 0 and 1 can be used here
        PredefinedMetricSpecification:
          PredefinedMetricType: LambdaProvisionedConcurrencyUtilization

line 50 should be:
TargetValue: 0.70 # Any value between 0.1 and 0.9 can be used here
see https://aws.amazon.com/blogs/aws/new-provisioned-concurrency-for-lambda-functions/

Here is my solution:
"DependsOn": ["MyFunctionAliaslive"]
I use the list of strings instead of string.
