Redash 5.0 'Internal Server Error'; where are the log files?

Spawned new EC2 instance using AMI.
Upgraded to 5.0
Trying to browse to the server address just gives a 500 error.

According to the ‘basic operations’ page

(regarding log files)

These instructions are not relevant for those who use our Docker based instances and should be updated. We will appreciate your help with updating this guide.

So where ARE these log files?

Are you sure you’re using a Docker based AMI? Because the Docker ones already come with V5, so you didn’t have to upgrade.

Anyway, if you’re on a new AMI: you can see logs by using the docker-compose logs command (you can narrow it by service and/or just the last X rows).
