Overflow
SPL Token · Custom(14) · 0xe
custom program error: 0xe
What it means
The operation would overflow the token amount (u64).
What to do
Reduce the amount — check for double-scaling by decimals in the client.
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 14 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.
