原因
Guardsで設定したsolPaymentをMint時に指定していないため。
「Public key mismatch」という内容だったため、Mintアドレスが間違ったのかと思ったが、今回のケースではMint時の引数が足りなかっただけだった。
Guardsで設定したら、mintArgsでも指定が必要（ということであってそう）。
Guardsはオンチェーンで管理しているので、トランザクション送信時にMinter側（Mintするユーザー）で一緒に設定（厳密にはInstruction）を投げないといけないっぽい。
対応
以下のようにmintArgsにsolPaymentを追加して解決。
await transactionBuilder()
.add(setComputeUnitLimit(umi, { units: 800_000 }))
.add(
mintV2(umi, {
candyMachine: candyMachine.publicKey,
// minter, // default to Umi's identity and payer
nftMint,
collectionMint: collectionMint.publicKey,
collectionUpdateAuthority: collectionUpdateAuthority.publicKey,
mintArgs: {
mintLimit: some({ id: 1 }),
// 以下を追加！
solPayment: some({ destination: umi.identity.publicKey }),
},
}),
)
.sendAndConfirm(umi);
