I an trying to send a transaction to RAYDIUM V4 program to remove liquid from an Liquidity Pool. However, I encountered an error with code 0x2e. From here: https://github.com/raydium-io/raydium-amm/blob/master/program/src/error.rs
I found out that the error is OrderAtSlotIsPlaced. But I am unable to find where the error comes from as there is nowhere in the raydium-amm codebase produce the error.
Is there anyone have any idea about this error? Where does it come from? How to fix?
Thank you.
