Unable to run basic test provided in documentation

Tried to use the test example mentioned here

Updated the path to load ABI as well
I did forc build and then cargo test

here’s the sway contract -

contract;
 
abi TestContract {
    #[storage(write)]
    fn initialize_counter(value: u64) -> u64;
 
    #[storage(read, write)]
    fn increment_counter(amount: u64) -> u64;
}
 
storage {
    counter: u64 = 0,
}
 
impl TestContract for Contract {
    #[storage(write)]
    fn initialize_counter(value: u64) -> u64 {
        storage.counter.write(value);
        value
    }
 
    #[storage(read, write)]
    fn increment_counter(amount: u64) -> u64 {
        let incremented = storage.counter.read() + amount;
        storage.counter.write(incremented);
        incremented
    }
}

Here’s the error i am getting

Hi, can you share your harness.rs file please and the version of fuels.

Hey sorry for the delayed response - here’s the harness.rs

use fuels::{prelude::*, types::ContractId};
 
// Load ABI from JSON
abigen!(TestContract, "out/debug/test-one-abi.json");
 
async fn get_contract_instance() -> (TestContract, ContractId) {
    // Launch a local network and deploy the contract
    let mut wallets = launch_custom_provider_and_get_wallets(
        WalletsConfig::new(
            Some(1),             /* Single wallet */
            Some(1),             /* Single coin (UTXO) */
            Some(1_000_000_000), /* Amount per coin */
        ),
        None,
    )
    .await;
    let wallet = wallets.pop().unwrap();
 
    let id = Contract::load_from(

@Chester-King is this issue resolved?
