Explanation

To publish VPC flow logs to Amazon CloudWatch Logs, the IAM role used by the flow logs must have permissions such as logs:CreateLogGroup, logs:CreateLogStream, and logs:PutLogEvents. If the logs:CreateLogGroup permission is missing, CloudWatch Logs cannot create or write to the log group, preventing the logs from appearing.
