Getting errors that JSON is not serializable for ClientExtensions, TakeProfitDetails & StopLossOnFill

• Exception: TypeError: Object of type 'ClientExtensions' is not JSON serializable
• Exception: TypeError: Object of type 'TakeProfitDetails' is not JSON serializable
• Exception: TypeError: Object of type 'StopLossOnFill' is not JSON serializable

Here is the code used to create LimitOrderRequest:

    takeProfitOnFillOrder = TakeProfitDetails(price=takeProfit)
    stopLossOnFill = StopLossDetails(price=stopLoss)
    clientExtensions= ClientExtensions(clientID="123", clientTag="ABC", clientComment = "new stratagy" )
    client = oandapyV20.API(access_token=apikey, environment=environment)
    ordr = LimitOrderRequest(instrument=instrument, 
                            units=units, 
                            price= openPrice, 
                            takeProfitOnFill=takeProfitOnFillOrder, 
                            stopLossOnFill=stopLossOnFill,
                            clientExtensions=clientExtensions
                            )
    r = orders.OrderCreate(accountID = account, data=ordr.data)
    rv = client.request(r)
    print(r.response)

Finally, I figured out the issue with my code: passed the ClientExtensions, TakeProfitDetails & StopLossOnFill object as object and now converted to JSON string using "data" property.

    takeProfitOnFillOrder = TakeProfitDetails(price=takeProfit)
    stopLossOnFill = StopLossDetails(price=stopLoss)
    clientExtensions= ClientExtensions(clientID="123", clientTag="ABC", clientComment = "new stratagy" )
    client = oandapyV20.API(access_token=apikey, environment=environment)
    ordr = LimitOrderRequest(instrument=instrument, 
                            units=units, 
                            price= openPrice, 
                            takeProfitOnFill=takeProfitOnFillOrder.data, 
                            stopLossOnFill=stopLossOnFill.data,
                            clientExtensions=clientExtensions.data
                            )
    r = orders.OrderCreate(accountID = account, data=ordr.data)
    rv = client.request(r)
    print(r.response)
