Rust SDK Error: Calling payable functions fails in RustSDK doesn't work

I am adapting the docs in calling a payable function with base asset and using this code snippet to call payable function

// harness.rs
use fuels::{prelude::*, types::ContractId};

abigen!(Contract(name="MyContract", abi="out/debug/test_asset-abi.json"));


#[tokio::test]
async fn test_harness() {
    // Test code here
    let (instance, _id,wallets) = get_contract_instance().await;
    let wallet_1 = wallets.get(0).unwrap();
    let call_params = CallParameters::default().with_amount(1);
    // help here
    let result= instance.clone().with_account(wallet_1.clone()).methods().deposit().append_variable_outputs(1).call_params(call_params).unwrap().call().await.call().unwrap();
    let result2 = instance.methods().test_deposit_asset_id_same_generated().call().await.unwrap().value;
    assert_eq!(result, result2);
}


async fn get_contract_instance() -> (MyContract<WalletUnlocked>, ContractId,Vec<WalletUnlocked>) {
    // Launch a local network and deploy the contract
    let wallets = launch_custom_provider_and_get_wallets(
        WalletsConfig::new(
            Some(3),             /* Three wallets */
            Some(1),             /* Single coin (UTXO) */
            Some(1_000_000_000), /* Amount per coin */
        ),
        None,
        None,
    )
    .await
    .unwrap();
 
    let wallet = wallets.get(0).unwrap().clone();
    
    let id = Contract::load_from(
        "./out/debug/test_asset.bin",
        LoadConfiguration::default(),
    )
    .unwrap()
    .deploy(&wallet, TxPolicies::default())
    .await
    .unwrap();
 
    let instance = MyContract::new(id.clone(), wallet);
 
    (instance, id.into(),wallets)
}

This is my main.sw

// Constant Product AMM - Uniswap V2.
contract;

use std::{
    constants::ZERO_B256,
    hash::sha256,
    asset::transfer,
    hash::Hash,
    asset_id::AssetId,
    asset::{
        burn,
        mint_to,
    },
    contract_id::ContractId,
    call_frames::{
        msg_asset_id,
    },
    context::msg_amount,
    string::String,
};
 

abi MyContract {
    #[storage(read, write)]
    fn deposit()-> b256;
    
    #[storage(read)]
    fn test_deposit_asset_id_same_generated() -> b256;
}


impl MyContract for Contract {
    #[storage(read, write), payable]
    fn deposit() -> b256 {

        let owner = msg_sender().unwrap();
        let asset_id = msg_asset_id().bits();
        let address_from_b256: Address = Address::from(asset_id);
        asset_id
    }


    #[storage(read)]
    fn test_deposit_asset_id_same_generated() -> b256  {
        let token_id = "b256::zero()";
        let token_address =  AssetId::base();
        let sub_id = sha256((token_address, token_id));

        
        let asset_id: b256 = AssetId::new(ContractId::this(), sub_id).bits();
        let address_from_b256: Address = Address::from(asset_id);
    
        asset_id
        
    }

}

This is the error:

error[E0599]: the method `methods` exists for struct `MyContract<&WalletUnlocked>`, but its trait bounds were not satisfied
  --> tests/harness.rs:12:57

Please anyone, I am getting cancer from this :stuck_out_tongue:

Interesting, did someone change the docs? @david for this code snippet to call payable function

I just revisted the site and it changed from

let result= instance. Clone().with_account(wallet_1.clone()).methods().deposit().append_variable_outputs(1).call_params(call_params).unwrap().call().await. Call().unwrap();`

to

let result= instance.clone().with_account(wallet_1.clone()).methods().deposit().append_variable_outputs(1).call_params(call_params).unwrap().call().await. Call().unwrap();

Can we have a page update for each documentation page so that we know when it was updated?

Anyways, I reupdate the code with adding .value.

use fuels::{prelude::*, types::ContractId};

abigen!(Contract(name="MyContract", abi="out/debug/test_asset-abi.json"));


#[tokio::test]
async fn test_harness() {
    // Test code here
    let (instance, _id,wallets) = get_contract_instance().await;
    let wallet_1 = wallets.get(0).unwrap();
    let call_params = CallParameters::default().with_amount(1);
    // help here
    let result= instance.clone().with_account(wallet_1.clone()).methods().deposit().append_variable_outputs(1).call_params(call_params).unwrap().call().await.unwrap().value;
    let result2 = instance.methods().test_deposit_asset_id_same_generated().call().await.unwrap().value;
    assert_eq!(result, result2);
}


async fn get_contract_instance() -> (MyContract<WalletUnlocked>, ContractId,Vec<WalletUnlocked>) {
    // Launch a local network and deploy the contract
    let wallets = launch_custom_provider_and_get_wallets(
        WalletsConfig::new(
            Some(3),             /* Three wallets */
            Some(1),             /* Single coin (UTXO) */
            Some(1_000_000_000), /* Amount per coin */
        ),
        None,
        None,
    )
    .await
    .unwrap();
 
    let wallet = wallets.get(0).unwrap().clone();
    
    let id = Contract::load_from(
        "./out/debug/test_asset.bin",
        LoadConfiguration::default(),
    )
    .unwrap()
    .deploy(&wallet, TxPolicies::default())
    .await
    .unwrap();
 
    let instance = MyContract::new(id.clone(), wallet);
 
    (instance, id.into(),wallets)
}

Instead of having the error @david from above, I got a new error:

   Compiling test_asset v0.1.0 (/home/lokicheck/Desktop/test_asset)

Weird that after changing codes in Sway Contract, we must run forc build before running cargo test everytime. Can we ensure that running cargo test would run forc build first?
