custom program error: 0x18ba
What it means
Wrong number of constituents passed to instruction
What to do
The error name is the program's own diagnosis. Paste the failed transaction into TxWhy to see which instruction raised it and with which accounts.
Have the transaction that failed with this?
Paste its signature. TxWhy shows the exact instruction and inner call that raised the error, and rebuilds the transaction when the cause is one it can fix (compute limit, expired blockhash, priority fee, stale swap quote).
