custom program error: 0x179a

What it means

Slippage: Would buy less tokens than expected min_tokens_out

What to do

Increase your slippage tolerance or reduce the trade size, then retry — the price moved between quote and execution.

TxWhy can repair this one

When the swap was routed through Jupiter, TxWhy replaces only the stale swap instruction with a current quote for the same tokens, amount and slippage tolerance, keeps every other instruction byte for byte, and proves the result passes simulation.
