/PiConnectAPI/TPSeries returning "Error Occurred : 1 "unknown request""

[Sbg03]

The /PiConnectAPI/TPSeries endpoint stopped working today (Monday 22 June). It was working fine on Friday 19 June.
Symptoms:

• All POST requests to /PiConnectAPI/TPSeries return:
  {"stat":"Not_Ok","emsg":"Error Occurred : 1 "unknown request""}
• The session token is valid — all other endpoints work correctly (GetQuotes, SearchScrip, EODChartData, PlaceOrder, etc.) with the same jKey.
• The error occurs regardless of payload format — we tested with and without ordersource, actid, with string/int intrv, with/without st/et, and all fail the same way.
  Payload we send (standard format used by NorenRestApiPy v0.0.20):
  jData={"ordersource":"API","uid":"USER","exch":"NSE","token":"26000","st":"1234567890","et":"1234567890","intrv":"1"}&jKey=TOKEN
  Could you please investigate what changed on your server over the weekend and restore the /TPSeries endpoint?
