如何讓現在 polkadotJS App 連到 Substrate v2.0.0?

在 polkadot js 内作 balance transfer 会报以下错误：

balances.transferKeepAlive 1002: Verification Error: Execution: Could not convert parameter `tx` between node and runtime: No such variant in enum MultiSignature: RuntimeApi, Execution: Could not convert parameter `tx` between node and runtime: No such variant in enum MultiSignature

在 polkadot js app 内加回 custom type:

{
  "Address": "AccountId",
  "LookupSource": "AccountId"
}

就可让 polkadot js app 连到 substrate / substrate-node-template v2.0.0。测试過能作 balance transfer 及 templateModule 内的 doSomething() 。

如果不设 custom types，会报错。
