For the lambda function to create log stream and publish logs to cloudwatch, the lambda execution role needs to have the following permissions.

    "Statement": [

            "Action": [
                "logs:CreateLogGroup",
                 "logs:CreateLogStream",
                 "logs:PutLogEvents"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:logs:*:*:*"
        }
    ]
}
