Getting BadRequest when placing order

At the start of some trading days (till around 9:30am), I often get a BadRequest when placing an order for a particular instrument. The return has no information about what parameters are wrong (if any), why its a bad request, etc.

For example, today I got BadRequest when placing this order:

PLACEORDER SELL NRML 1755 x NIFTY 23100 PE 10 MAR 26 @ 45.95


How can I diagnoze this issue without any other info than just a “BadRequest”?

Can you help me with diagnosis of this (and similar) error?
