When I try to send a grouped transaction with myalgo connect, the signing works fine,
const myAlgoConnect = new MyAlgoConnect();
const txnsToGroup = [ optinapp1txn, optinassettxn];
const groupID = algosdk.computeGroupID(txnsToGroup)
for (let i = 0; i < 2; i++) txnsToGroup[i].group = groupID;
const signedTxns = await myAlgoConnect.signTransaction(txnsToGroup.map(txn => txn.toByte()));
however, when I send the transaction
(await algodClient.sendRawTransaction(signedTxns.blob).do());
it displays the error TypeError: Argument must be byte array
Please help me!
