custom program error: 0x1780

This number has no meaning on its own. Each Solana program numbers its own errors, so 0x1780 is SwapNotSupported in Jupiter Aggregator v6 but CrossProgramInvokeViolation in Lighthouse. The meaning that applies is the one from the program that actually failed: the first Program … failed line in the transaction's logs. That is often not the program you called, but one it invoked, or a guard instruction your wallet added.

Don't guess: paste the transaction

TxWhy reads the logs, finds the program and the exact instruction that raised 0x1780, explains it, and rebuilds the transaction when the cause is one it can fix.
