Hi @MAHESH_RED_19289163,

It appears that an ISIN change has occurred for all the mentioned instruments. Please use the correct instrument keys as below:

  • NUVAMA → NSE_EQ|INE531F01023
  • CAMS → NSE_EQ|INE596I01020
  • CHOLAFIN → NSE_EQ|INE121A01024

Note: Instrument JSON files are refreshed daily as per the documentation: Instruments | Upstox Developer API
Please ensure you refresh the files on your end as well.

Thanks!
