Describe the bug

After following instructions in <Preview - Documentation>, I saw several sqlalchemy errors appeared, all indicating:

...
File "/usr/local/lib/python3.6/site-packages/sqlalchemy/engine/default.py", line 608, in do_execute
    cursor.execute(statement, parameters)
sqlalchemy.exc.ProgrammingError: (psycopg2.errors.UndefinedTable) relation "pages_page" does not exist
LINE 2: FROM pages_page
             ^

I ran the command described in the preview documentation to set up the DB:

docker exec -it invenioils_backend_1 /bin/bash
invenio@e34cadf4b303:/opt/invenio_app_ils/src$ ./scripts/setup

And this lead to the service becoming "responsive" but it still would not allow login.

Question:

Is login not supported in the preview (Docker) environment?
