DataException while GetInstruments()

ZK2689

I am getting a data exception while calling GetInstruments:

An exception of type 'KiteConnect.DataException' occurred in KiteConnect.dll but was not handled in user code
Unable to parse data. {"instrument_token":"6656001","exchange_token":"26000","tradingsymbol":"NIFTY","name":"","last_price":"0.0","expiry":"","strike":"0.0","tick_size":"-0.01","lot_size":"-1","instrument_type":"EQ","segment":"NSE","exchange":"NSE"}

Because of this I am not able to start my app.

Exactly. I am also facing the same problem with my app while calling Kite.GetInstruments("NSE"). Output window of VS says "Exception thrown: 'KiteConnect.DataException' in KiteConnect.dll" and Exception message is:

Unable to parse data. {"instrument_token":"6656001","exchange_token":"26000","tradingsymbol":"NIFTY","name":"","last_price":"0.0","expiry":"","strike":"0.0","tick_size":"-0.01","lot_size":"-1","instrument_type":"EQ","segment":"NSE","exchange":"NSE"}

As a result I am not able to update my instruments list.

I would like to second that but want to include the list of instruments that are causing this

1. 6656001
   
2. 6659841
   
3. 6658305
   
4. 6660353
   
5. 6659073
   
6. 6659585
   
7. 6665985
   
8. 6659329
   
9. 6658049
   

all of these cause exception of the exact message shown below
obviously with respective instrument information changed.

@ZK2689 @MadanGoyal in the mean time if you can change this line to what is below.

foreach (Dictionary<string, dynamic> item in instrumentsData )
{
                try
                {
                    instruments.Add(new Instrument(item));
                }
                catch( Exception ex )
                {
                        /// however you want to deal with excepion
                }
                
}

and recompile it.
this will avoid your app blowing up.

Thanks

I am also facing the same problem "KiteConnect.ParseException: Unable to parse the response. Use ResponseData property to get original response." ,

what is the solution for this ?

trade_then

@jegan if you can download the source from Clone or download

you can change the line as mentioned in above post. recompile, and reference .dll in your solution.

as a temporary solution to this problem.
Thanks

@trade_then , Thank you very much for your quick solution ,

but anyway mine is website, I don't have enough time to migrate my changes to web server,

I have to skip trading today, Hope the issue will be resolved soon !:(

MadanGoyal

Thanks @trade_then for a work around solution for this issue. Fortunately, my trading for the day won't be impacted by this issue because my app updates itself from previous trading day's instrument lists. Usually there are not many changes in a day, so I'll still go with it. Hopefully this issue is resolved soon...

trade_then

@Jegan I am also skipping placing orders today.
@MadanGoyal yaa my app also relies on previously stored instrument list in case something goes wrong.

Thanks

Hi,
There was some issue with instrument master dump we received today earlier. We are taking this up with the concerned team and investigating this.
You may have to re-download the latest instrument dump now to trade today.

trade_then

@sujith
Thanks, would do that.
Instrument list was bit small today compared to other days. it might be that.

Thanks
Regards

Jegan

@sujith , Please let us know once the issue is resolved , Thanks

sujith

@Jegan,
You won't be facing the issue anymore.

Jegan
