Im trying to make cross contracts calls on already deployed contract, im running the local subtrate node in debug mode, and im getting the following message when trying to preform cross contracts. Here is the error: ``` ThreadId(34) runtime::contracts: Execution finished with debug buffer: panicked at 'called `Result::unwrap()` on an `Err` value: CalleeTrapped', erc20/lib.rs:102:14 ``` Here is the ``` DeployedContract1 ``` cross call function code: ``` #[ink(message)] #[ink(selector = 40)] pub fn test(&self) -> u32 { self.platform_fee } ``` Here is ``` DeployedContract2 (erc20/lib.rs)``` function source code: ``` #[ink(message)] pub fn test1(&self,token_contract: AccountId) -> u32 { let my_return_value: u32 = ink_env::call::build_call::<<Self as ::ink_lang::reflect::ContractEnv>::Env>() .callee(token_contract) <--- ERROR points here .gas_limit(50000) .transferred_value(0) .exec_input( ink_env::call::ExecutionInput::new(ink_env::call::Selector::new([0, 0, 0, 40])), ) .returns::<ink_env::call::utils::ReturnType<u32>>() .fire() .unwrap(); my_return_value } ```
