Seems to be a problem with the setup of the Postgres DDBB. Could you explain further? Did you create an .env and change the values?

[adilmohak]

@sahal-git make sure you installed PostgreSQL and it's running

[adilmohak]

@sahal-git You're not engaging with this conversation, so I assume the problem is fixed and I will close this issue.
