DataException while GetInstruments()

ZK2689
ZK2689 in .Net API client
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

    @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

    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...

    @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.
