Hi @tyler_5201
The underlying error is that there is no connection string, as you noticed.
The connection string is stored in a file (/var/proget/database/.pgsqlconn) that should be accessible to the container. I haven't tested it, but I guess if file is missing or deleted, then I suppose you might run into these issues.
It should be created on startup of a new container, however. So it's kind of weird. I think you'll want to "play" with it a bit, since there's clearly something going on with your permissions I'm thinking.
Note that the connection string can also be specified as an environment variable, but I don't think that applies here since you're trying to configure the embedded datbase:
