This issue is created as a reference.
Sails js - the framework Konga is built upon - won't let the app alter database tables when running in production mode.
This is a failsafe to protect against inadvertently damaging your production data during deployment.
More info here .
To get around that for now, you will need to start Konga in develoment mode the first time only. That way the app will be able to create the needed db tables.
You can do that by setting the NODE_ENV environment variable to development
