Cannot run on aws eks

Troubleshooting
1

I followed the official kubernates installation guide but i failed to run it on amazon eks.

I am using external database and s3 as external file storage.

The database connection seems okay.

There are couple of errors, one states that it failed to connect the smtp server and other is about the license issue.

I am not using any smtp and Enterprise license.

Steps to reproduce

Latest version: 5.31.0

It seems that your database is not the correct version for the Mattermost instance that you have installed, can you provide further insight into the setup and version of your database?

Also @ahmaddanial would you be able to provide reference to the correct location/procedure to follow to upgrade the database schema?
