    bot.infinity_polling()

dbworker:

    with Vedis(config.db_file4) as db4:
        try:
            return db4[user_id].decode()  
        except KeyError: 
            return

            return True

            db[user_id] = value
            return True
        except:
            return False

config:

from enum import Enum
Token='1419935533:AAG5blXisxySbyZHgYWcSwIC8P_9iehCOHY'
db_file = "database.vdb"
db_file2 = "database2.vdb"
class States(Enum):
    S_INFO= "0"  
    S_MENU = "1"
    S_GL= "2"
    S_AMOUNT='3'
    S_OPLATI='4'

error:
module 'dbworker' has no attribute 'get_md'

in the menu function, I save the id of the messages sent by the bot to the database in order to delete these messages later.

config and dbworker are in the same folder with the main code

(I did not present all the code, but I think this is enough to see the problem, if you need to add something, write)

I ask you for help
thanks!
