@s237783 Intermittent issue caused by service outage.

@pankjsingh1028 Retry after recreating a new API key by clicking the refresh button next to API key in your Smart API account.

@abhay15-akshukla-0 As mentioned on https://smartapi.angelbroking.com/docs/Exceptions, this is an "Internal Server Error", most probably an intermittent issue because of service disruption.

@kavita-0

let web_socket = new WebSocketV2({ jwttoken: 'JWT_TOKEN', apikey: 'API_KEY', clientcode: 'Client_code', feedtype: 'FEED_TYPE', }); // for mode, action and exchangeTypes , can use values from constants file. web_socket.connect().then((res) => { let json_req = { correlationID: 'correlation_id', action: 1, mode : 1, exchangeType: 1, tokens: ["123"], }; web_socket.fetchData(json_req); web_socket.on('tick', receiveTick); function receiveTick(data) { console.log('receiveTick:::::', data); } });

Try this official sample code mentioned in the README.md of https://github.com/angel-one/smartapi-javascript

@pradulgupt82 Sync your system time and try again. Sometime this issue happens, just try again after 1 min, as TOTP is valid for 60 seconds.

@adhiraj Once you create a SmartApi app, all permissions are activated and there is no further need of activation of any market feed specific access.

@1059689 Server date and time might be out of sync and might be causing incorrect TOTP generation.

@cts Scrip Master is the master list of all the scrips. No token for Nifty Ind Defence is available as of now in smart api.
