Description

When attempting to resolve a peer by username, the function get_peer_by_username in the storage.py module is raising a KeyError due to the absence of the key "last_update_on" in the returned result. This issue likely stems from incomplete data or an unexpected format in the database.

Steps to reproduce

1. Attempt to resolve a peer by username.
2. Encounter a KeyError due to the absence of "last_update_on" key in the returned result.

Code example

from pyrogram import Client
from typing import Union

async def get_chat() -> None:
    async with Client("my_account") as app:
        try:
            chat: Union[None, dict] = await app.get_chat("pir11")
            if chat:
                print(chat)
            else:
                print("Chat not found.")
        except Exception as e:
            print("An error occurred:", e)

def main() -> None:
    get_chat()

if __name__ == "__main__":
    main()
