Running mint locally along with wallet. Pay lightning invoice to mint tokens. After paying invoice, ran balance command and getting expected balance. After confirming wallet had a balance, send command panicked. It seems it tried to access filteredKeySets slice which is not initialized.

in wallet: ~ balance You have balances in 1 keysets: Keysets: [MhH6M+GDd1/l] Balance: 76 sat URL: http://localhost:3338

~ send 10 MhH6M+GDd1/l panic: runtime error: index out of range [0] with length 0
