Seed too long
System Program · Custom(4) · 0x4
custom program error: 0x4
What it means
A seed used to derive the address exceeds 32 bytes.
What to do
Shorten the seed, or hash it to 32 bytes before deriving the address.
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 4 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.
