custom program error: 0x13

What it means

This instruction only works on native (wSOL) accounts.

What to do

Use a wrapped-SOL account for this operation.

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 19 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.
