Hi I am facing the below error intermittently. Please help me resolve it.
kiteconnect.exception.DataException: Unknown-Content -Type (text/html) with response: BAD Gateway Error

    Are you trying to download complete instrument list, too frequently?
    Complete instrument list is a memory heavy file, it should be downloaded once at a day start at your end in DB or to excel, etc file and same should be used further instead of making multiple requests to instrument file.

    Hi Rakeshr thanks for your reply. I am only accessing few instruments(Options) based on the strike price. If you need i can share my entire code for your analysis. Also this error is intermittent.

    It is a huge data dump, you need to download this data once a day and use that as the source.
  • sujith
    You shouldn't be fetching that every now and then.

    Thanks Sujith. Can you please let me know how can i filter Banknifty alone from this dump instead of fetching entire NFO data. I am using this piece of code to get the latest weekly expiry date.

    def weekly_expiry():
    data = kite.instruments('NFO')
    x = []
    for i in range(len(data)):

    x = list(set(x))

    if <= x[0].month:
    expiry_date = x[0]

    if x[0].month == x[1].month:
    if x[0].month < 10:
    expiry_date_month = str(x[0].month)
    return x[0].strftime('%y') + x[0].strftime('%#m') + x[0].strftime('%d')
    expiry_date_month = ((datetime.strptime(str(expiry_date.month), "%m")).strftime("%b"))[0]
    stringDate = str(expiry_date).split('-')
    formatedDate = f"{stringDate[0][2:]}{expiry_date_month.upper()}{stringDate[2]}"

    if x[0].month != x[1].month:
    expiry_date_month = ((datetime.strptime(str(expiry_date.month), "%m")).strftime("%b"))
    stringDate = str(expiry_date).split('-')
    formatedDate = f"{stringDate[0][2:]}{expiry_date_month.upper()}"

    return formatedDate
