@YedilSerzhan: I tried to create the database locally following your description. However, I get the app.py script running, because of a db connection error.
I will list more information below:

my db_confing:

$ cat db_config.py
DB_CONFIG = {
    'USERNAME': 'teresa',
    'PASSWORD': 'hallo',
    'DB_NAME': 'dnapi'
}

my enviorment:

$ conda list
