Autoscale ProvisionedConcurrentExecutions AWS Lambda DependsOn value null - amazon-web-services

Question

Im trying to add auto scaling to the Provisioned Concurrency configuration for our Lambdas on AWS.
Im having trouble with the DependsOn: value for the Lambda target it doesnt seem recognize the resource im passing in and says its null. In the example from AWS its using AutoPublishAlias which isnt an option for me. https://aws.amazon.com/blogs/aws/new-provisioned-concurrency-for-lambda-functions/
Am I referencing incorrectly?

Solution
Answer was to reference the logical id of the AWS::Lambda::Alias resource I created which in this case was
DependsOn: LambdaAlias
The doc was using AutoPublishAlias which didnt require the creation of a resource AWS::Lambda::Alias so config needed is slightly different

Answer 1

Have you tried just using the name of the resource for the LambdaAlias
I feel DependsOn: LambdaAlias should do the trick
You are using plain Cloudformation where the article you refer to is using AWS SAM.

Answer 2

since you are not using any AutoPublishAlias the format
{functionLogicalResourceName}Alias{aliasName}
should work for you..
In the sample you have provided. You have not provided the part which is deploying Lambda so if we assume your lambda logical id is MyLambda you should
DependsOn: MyLambdaAliaslive
