Unsupported getDefaultProvider network

[caicaishmily]

Hey, I config the monad test network, but I got some error like:

unsupported getDefaultProvider network (operation="getDefaultProvider", network={"name":"Monad Testnet","chainId":10143}, code=NETWORK_ERROR, version=providers/5.8.0)

{
  reason: 'unsupported getDefaultProvider network',
  code: 'NETWORK_ERROR',
  operation: 'getDefaultProvider',
  network: {
    name: 'Monad Testnet',
    chainId: 10143
  }
}

here are my config:

EthersModule.forRoot({
    network: {
      name: 'Monad Testnet',
      chainId: 10143,
    },
    alchemy: "https://monad-testnet.g.alchemy.com/v2/balabalabablajshanabab"
  })
