Error generating token in FastAPI with Bcrypt

I am watching a tutorial on FastAPI, where it switched the database from SQLite to PostgreSQL, before generating a token. It was working before but now it has an error, shown below

return bcrypt.checkpw(password=password_byte_enc, hashed_password=hashed_password) TypeError: argument 'hashed_password': 'str' object cannot be converted to 'PyBytes'

I think this is the code concerning the error:

def get_password_hash(password):    # return bcrypt_context.hash(password)    pwd_bytes = password.encode('utf-8')    salt = bcrypt.gensalt()    hashed_password = bcrypt.hashpw(password=pwd_bytes, salt=salt)    return hashed_passworddef verify_password(plain_password, hashed_password):    password_byte_enc = plain_password.encode('utf-8')    return bcrypt.checkpw(password=password_byte_enc, hashed_password=hashed_password)

The entirity of the auth.py file is here https://pastebin.com/mHcd0YLU

This is where I input the username and password to generate a token but it gets an error:
