Hi,
Are you using proxy wallet or metamask wallet keys? If you use a correct signer, I don't think the issue happens

[JositopBot]

I've tried both.

If I use Metamask, the signature type is 0, and if I use Magic, I put 1 and also fill in the proxy_wallet_address.

[justshiftjk]

when we use metamask, the signature type should be 2, not 0
