validation service: xmtp_id::associations::verified_signature: Smart contract wallet signature is invalid None

[mkysel]

The validation service throws
xmtp_id::associations::verified_signature: Smart contract wallet signature is invalid None

Seen by testnet partners and us.

The None here is really weird:

        if response.is_valid {
            // set the block the signature was validated on
            *block_number = response.block_number;

            Ok(Self::new(
                MemberIdentifier::eth(account_id.get_account_address())?,
                SignatureKind::Erc1271,
                signature_bytes.to_vec(),
                Some(account_id.get_chain_id_u64()?),
            ))
        } else {
            tracing::error!(
                "Smart contract wallet signature is invalid {:?}",
                response.error
            );
            Err(SignatureError::Invalid)
        }
