Logs from Serverless framework is not showing on AWS CloudWatch

Question

I am using serverless framework, AWS CodeCommit, CodeBuild, and CodePipeline. When I push my code and CodeBuild starts to deploy it, I don't get any feedback or logs from serverless framework inside the CloudWatch log groups.

I am using the default service roles for CodeBuild and CodePipeline which are created by AWS when I first created a new PipeLine and CodeBuild. Both of those roles include polices for CloudWatch and create log groups as follows:

CodeBuild

"Statement": [
    {
        "Effect": "Allow",
        "Resource": [
            "arn:aws:logs:us-west-2:*****:log-group:/aws/codebuild/sis-notes-backend-codebuild",
            "arn:aws:logs:us-west-2:*****:log-group:/aws/codebuild/sis-notes-backend-codebuild:*"
        ],
        "Action": [
            "logs:CreateLogGroup",
            "logs:CreateLogStream",
            "logs:PutLogEvents"
        ]
   },

CodePipeline

"Action": [
            "elasticbeanstalk:*",
            "ec2:*",
            "elasticloadbalancing:*",
            "autoscaling:*",
            "cloudwatch:*",
            "s3:*",
            "sns:*",
            "cloudformation:*",
            "rds:*",
            "sqs:*",
            "ecs:*"
        ],
        "Resource": "*",
        "Effect": "Allow"
    },

And this is the output of CloudWatch log groups. As you can see that I've wrote rubbish in the deploy code in order to get an error or failed response back from Serverless, but I got nothing just empty lines.

sls deploy -v will only output the version information and exit. It's a greedy match.

Change the -v flag to --verbose and this will work.

Example:

➜  js-library-test sls deploy -v
Running "serverless" from node_modules
Framework Core: 3.1.1 (local) 3.12.0v (global)
Plugin: 6.0.0
SDK: 4.3.1

➜  js-library-test
