old Logs are gone after deploying new version #3441

I am very new person to parse-server.

I am using default logger on aws beanstalk.
But after deploying new version to beanstalk, old logs are gone on dashboard.
I cannot see the whole logs and cannot follow the issue.

Is anybody who know "how to store logs permanently or (specific time window ex) 1month)" on aws beanstalk.

thank you for helping
