I want create a new git repository (AWS codeCommit) with any source from a zip file.

I follow AWS official documentation here but I do not find any restriction (20 MB).

Cloudformation:

  MyCodeCommit:
    Type: AWS::CodeCommit::Repository
    Properties:
      RepositoryName: !Sub ${StackName}-myrepo-codecommit
      RepositoryDescription: This is a repository for the myApp part.
      Code:
        S3:
          Bucket: !Sub "${AWS::AccountId}-${StackName}-myApp-source"
          Key: "myApp.zip"

I have this error:

Code archive supplied cannot be more than 20 MB compressed

Is it possible to configure this with more than 20 MB?
