Facing issues while genarating signature that could interact with smart contract

[SyedImam1998]

Hi Team,

I am trying generate a signed tx that would change the state of the smart contract but not sure why i am not able to generate signed transaction.

I am Getting this Error:

[Error: error getting RLP transaction in CreateTxSignature: invalid value ]

Smart Contract: 0x28983feD81de3548d2e4C110BCB997A4879dA478 - This is the smart contract that i trying to interact deployed on Goerli Test Network.

Below is my React-Native code:

const setNameFunc = async () => {
    const setNameFunction = contract.interface.getFunction('setName');
    const setNameTransactionData = contract.interface.encodeFunctionData(setNameFunction,['John Doe']);
    const cleanedAddress = addressName.replace('networks/ethereum-goerli/addresses/','',);
    const nonce = await provider.getTransactionCount(cleanedAddress);
    const gasInfo = await provider.getFeeData();
    const initialTx = {
      ChainID: '0x5',
      Nonce: nonce,
      MaxPriorityFeePerGas: gasInfo.maxPriorityFeePerGas?.toHexString(),
      MaxFeePerGas: gasInfo.maxFeePerGas?.toHexString(),
      Gas: 21000,
      To: '0x28983feD81de3548d2e4C110BCB997A4879dA478',
      Data: setNameTransactionData,
      Value: '',
    };
    Signtx(initialTx);
  };

const Signtx = async (initialTx: any) => {
    try {
      console.log('started');
      await initMPCSdk(true);
      await initMPCKeyService(apiKeyName, privateKey);
      await initMPCWalletService(apiKeyName, privateKey);
      const retrievedAddress = await getAddress(addressName);
      const keyName = retrievedAddress.MPCKeys[0]!;
      const resultTx = initialTx as Transaction;
      await createSignatureFromTx(keyName, resultTx);
      const pendingSignatures = await pollForPendingSignatures(deviceGroupName);
      await computeMPCOperation(pendingSignatures[0]!.MPCData);
      let signatureResult = await waitPendingSignature(
        pendingSignatures[0]!.Operation,
      );
      const signedTxResult = await getSignedTransaction(
        resultTx,
        signatureResult,
      );
      setSignedTx(signedTxResult);
      const txReceipt = await provider.sendTransaction(
        signedTxResult.RawTransaction,
      );
      console.log('Transaction hash:', txReceipt.hash);
    } catch (error) {
      console.log('error');
      console.log(error);
      throw new Error('Invalid initialTx value');
    }
  };

Can someone please help me here.
