500 Internal Server Error

[rwanwork]

Hi,

I'm trying to get this work and similar to Issue #16, I'm encountering a "500 Internal Server Error". I ran it in non-daemon mode (i.e., without -d), and I'm getting lots of messages on the screen. I noticed this message before I accessed the site:

Afterwards I accessed http://localhost:5000 and I got this message:

I've tried both the default password stored in docker-compose.yml and test1337 from Issue #16.

I then started up the container and ran docker exec -it mesa_dna_sim_postgres_1 bash (as mentioned in Issue #16) to try to change the password and I got this:

bash-5.1# psql -U postgres
psql (14.5)
Type "help" for help.

postgres=# \password dna_sim
Enter new password for user "dna_sim": 
Enter it again: 
ERROR:  role "dna_sim" does not exist

so, it seems like this user does not exist? I'm not sure what I can do next... Any suggestions would be appreciated; thank you!
