custom program error: 0x2

What it means

The mint account is not valid.

What to do

Verify the mint address and that it was created by the token program in use.

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 2 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.
