Assert Revert error logs

What does this error mean? I am testing if msg_asset_id().bits() is the same as AssetId::new(ContractId::this(), sub_id).bits();

This is my code:

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;
}

storage {
    deposits: StorageMap<(Identity, b256), u64> = StorageMap {},
}



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

        let owner = msg_sender().unwrap();
        let asset_id = msg_asset_id().bits();
        asset_id
    }


    #[storage(read)]
    fn test_deposit_asset_id_same_generated() -> b256 {
        let token_id = b256::zero();
        let token_address = ZERO_B256;
        let sub_id = sha256((token_address, token_id));

        let owner = msg_sender().unwrap();
        
        let asset_id: b256 = AssetId::new(ContractId::this(), sub_id).bits();
    
        asset_id
        
    }

}
#[test]
fn test_meaning_of_life() {
    let instance = abi(MyContract, CONTRACT_ID);

    let result = instance.deposit();
    let result2 = instance.test_deposit_asset_id_same_generated();

    assert(result == result2);
}

Tried importing use std::assert::assert also doesn’t work
