Error Code: AB1004, Error Message: "Something Went Wrong, Please Try After Sometime"

[S237783]

Dear Angel One Support Team,

I am using the Angel One SmartAPI (Python SDK) for fetching historical candle data. However, I am consistently receiving an error for my requests.

Error Code: AB1004

Error Message: [E 260121 09:38:53 smartConnect:246] Error occurred while making a POST request to https://apiconnect.angelone.in/rest/secure/angelbroking/historical/v1/getCandleData.

The session is active, and other APIs are working fine, but the getCandleData endpoint keeps failing with the same error code. I have attached a screenshot of the error log for your reference.
