Describe the bug

Having this custom sol struct with i128 numbers, i find that snippet 1 works and it results in a correct hash, but snippet 2 doesnt, showing a "number out of range" error. i think this is cause snippet2 function will use serde::json serialization while first 1 wont

struct Order {
    bytes32 sender;  
    int128 priceX18;  
    int128 amount;
    uint64 expiration;
    uint64 nonce;                
}

Snippet 1 let sig: FixedBytes<32> = msg.eip712_signing_hash(&(domain.clone())); info!("sig 1 {:?}", sig); Snippet 1
info!("st {:?} {:?}", TypedData::from_struct(&msg, Some(domain)).eip712_signing_hash(), sig); info!("sig 2 {:?}", sig);
