Extrinsic verification error:... FailedToConvertParameter "validate_transaction" Could not decode MultiAddress

Question

非常抱歉这个新手问题...

我的计划是将 flippers 合约部署到 substrate-node-template ((https://github.com/substrate-developer-hub/substrate-node-template)；特别是 tag = 'monthly-2021-05'.

我复制了 canvas-node (https://github.com/paritytech/canvas-node) 上的内容；任何东西 pallets_contracts*,
其中包括 runtime lib.rs:

parameter_types! {
  ...
  pub const MaxDepth: u32 = 100;
  pub const MaxValueSize: u32 = 16_384;
  pub const MaxCodeSize: u32 = 2 * 1024;
}

impl pallet_contracts::Config for Runtime { 
  ... 
  type MaxDepth = MaxDepth;
  type MaxValueSize = MaxValueSize;
  type MaxCodeSize = MaxCodeSize;
}
...

impl_runtime_apis! {
  impl pallet_contracts_rpc_runtime_api::ContractsApi< 
   Block,
   AccountId, 
   Balance, 
   BlockNumber, 
   Hash
> for Runtime {
  ... 
}

和noderpc.rs

io.extend_with(
    ContractsApi::to_delegate(Contracts::new(client.clone()))
);

项目将生成，但是当我单击 canvas-ui, a warning would appear:

上的 SignAndSubmit 按钮时

 RPC-CORE: submitAndWatchExtrinsic(extrinsic: Extrinsic): ExtrinsicStatus:: 1002: Verification Error: Runtime error: Execution failed: ApiError(FailedToConvertParameter { function: "validate_transaction", parameter: "tx", error: Error { cause: None, desc: "Could not decode `MultiAddress`, variant doesn\'t exist" } }): RuntimeApi, Execution failed: ApiError, FailedToConvertParameter { function: \"validate_transaction\", parameter: \"tx\", error: Error { cause: None, desc: \"Could not decode `MultiAddress`, variant doesn\\'t exist\" } }

我做错了什么？或者 Canvas-UI 仅适用于 Canvas-Node？

感谢@NukeManDan，我在 polkadot.js.org/apps 中进入设置下拉菜单 -> 开发人员，然后更改为：

{ 
  "Address": "MultiAddress", 
  "LookupSource": "MultiAddress" 
}

之后，我进入开发者下拉菜单 -> 合同，点击 上传和部署代码 按钮并选择我的 .contract 文件.

是的，我停止使用 Canvas UI。
