@ANAND_1674204 This issue seems to be specific to your local environment. This error occurs when the pandas library attempts to read data from “https://assets.upstox.com” but fails to verify the SSL certificate. The system is unable to retrieve the local issuer certificate, indicating that your machine is either missing the required root Certificate Authority (CA) or unable to verify it.

If your system is missing root certificates, try below and let me know if it works, Thanks
