Invalid Input: Group transaction does not need to be signed by Wallet user

1

Hello, I need some help regarding solving this error.
I have two transactions, one is signed by logicSign and other is supposed to be signed using WalletConnect.

const txnsToSign = txsToSign.map(txn => {
          const encodedTxn = Buffer.from(algosdk.encodeUnsignedTransaction(txn)).toString('base64');
          return {
            txn: encodedTxn,
          };
        });
        const txnsNotToSign = txsNotToSign.map(txn => {
          const encodedTxn = Buffer.from(algosdk.encodeUnsignedTransaction(txn)).toString('base64');
          return {
            txn: encodedTxn,
            signers:[]
          };
        });

These transaction are sent to

      const result = await this.walletConnect.sendCustomRequest(request);

And I receive this error.

Invalid Input: Group transaction does not need to be signed by Wallet user.

Can someone explain what this error means and what am I doing wrong?

Can you provide the full code generating request?
Can you show the content of request?

let requestObj= [];
 
txnsToSign.forEach(txn => requestObj.push(txn));
txnsNotToSign.forEach(txn => requestObj.push(txn));
        
 requestParams = [requestObj];
 const request = formatJsonRpcRequest('algo_signTxn', requestParams);
 const result = await this.walletConnect.sendCustomRequest(request);

I converted to JSON your two transactions using the Algorand software msgpacktool:

As you can see the first transaction has "grp": {}, which is not authorized, while the second transaction has not "grp".
This means you have an issue in the way you assigned the group ID.

Did you follow Atomic transfers - Algorand Developer Portal ?

Thank you so much,
I was assigning groupID in the wrong way
