SQL fejl

Jeg får en fejl i SQL delen af dette stykke kode, resten virker. Hvad er der galt.

def mainRate_v1(base_currency):
    # Define the API endpoint and parameters
    api_endpoint = "https://openexchangerates.org/api/latest.json"
    params = {"app_id": '****', "base": base_currency}

    # Send a GET request to the API endpoint and parse the JSON response
    response = requests.get(api_endpoint, params=params)
    exchange_rates = response.json()["rates"]

    # Connect to the Access database
    conn_str = (
      r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};'
      r'DBQ=C:\Users\peter\OneDrive\Investering\Aktiver_Etoro.accdb;'
    )
    cnxn = pyodbc.connect(conn_str)
    cursor = cnxn.cursor()

    # Define the INSERT INTO statement

    # Loop through the exchange rates and insert them into the database
    for currency, rate in exchange_rates.items():
        # Execute the SQL statement with the values
        cursor.execute("INSERT INTO ExchangeRates (Currency, Rate, base_currency) VALUES (?, ?, ?)", (currency, rate, base_currency))
        # currency, base_currency text field
        # rate is double feild

    # Commit the changes and close the database connection
    cnxn.commit()
    cursor.close()
    cnxn.close()
