IndexOutOfBounds
Lighthouse · Custom(6006) · 0x1776
custom program error: 0x1776
What it means
The guard points at an index that does not exist. Lighthouse is the assertion program wallets and trading apps append to a transaction as a safety guard.
The program's own message: “IndexOutOfBounds”
What to do
This is a problem in how the app built its guard, not in your funds or the market. Retry from the app; if it repeats, report it to the app with this transaction.
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).
Code 6006 means something else in other programs
Custom codes are private to each program. Check which program actually raised it: it is the innermost failed call, not necessarily the program you called.
