Missing or invalid. request() method: tron_signTransaction'

[kstulgys]

I'm unable successfully use same code as in tron example

I get these errors:

// request() -> isValidRequest() failed'
// Missing or invalid. request() method: tron_signTransaction'

     
     const network = isTestnet() ? TronChains.Nile : TronChains.Mainnet;

     const signedTransaction = await client!.request<{ result: any }>(
        {
          method: "tron_signTransaction",
          params: { address, transaction: transaction.transaction },
        },
        `tron:${network}`
      );
