Problem with send transaction logged with maiar app

[joansala13]

When i login in my Dapp with web wallet, i can send transactions and can query smart contract with no problems, but when i logged with maiar app, when i try to send transaction to my smart contract the console show me:
Uncaught (in promise) TypeError: transaction.send is not a function
at WalletConnectProvider. (walletConnectProvider.ts:137:1)

I send the transaction with provider like:
provider.sendTransaction(tx);

I use erjs 10.1.0 for my Dapp, but i have this problem... any idea or help?

Hello @joansala13!

Indeed, the Transaction object does not have the send() function anymore. Furthermore, walletConnectProvider does not have the function sendTransaction (it has been removed).

I assume you are using dapp-core (which currently references erdjs v9.x), and offers you an instance of a previous version of the signing provider.

Please broadcast the transaction directly to the API - or use one of the default Network Providers, as depicted here:

https://docs.elrond.com/sdk-and-tools/erdjs/erdjs-cookbook/#broadcasting-transactions

That is, do not use the wallet connect provider to broadcast the transaction.

Does this resolve your issue?

Thanks for the answer @andreibancioiu ,

I try the solution mentioned, i inspired i elrond dapp template in ping transaction, i do copy&paste of the transaction, change the contractAddress in my config (equal of dapp-tempalte, in this in local, transaction work) and in my code say:
error signing transaction TypeError: elrondnetwork_erdjs__WEBPACK_IMPORTED_MODULE_1_.Nonce is not a constructor

the only difference i see is the version of erdjs in my package.json... i need the downgrade for this?

thanks!

Hello @joansala13!

Indeed, an option would be to downgrade the erdjs reference until dapp-template is updated to use erdjs v10, as well.

However, do you think you can post the code snippet that triggers the error? It's true that new Nonce() isn't available anymore in erdjs 10: https://docs.elrond.com/sdk-and-tools/erdjs/erdjs-migration-guides/#nonce-gas-limit-gas-price-chain-id

sure @andreibancioiu , this is a function i call from onClick button ->

  const handleStakeItem = async () => {
    const pingTransaction = {
      value: "1000000000000000000",
      data: "ping",
      receiver:
        "erd1qqqqqqqqqqqqqpgquvt728n40ssd8n2qns9jrlqpwq2jc4rj4cysfuj3ad",
    };
    await refreshAccount();

    const { sessionId /*, error*/ } = await sendTransactions({
      transactions: pingTransaction,
      transactionsDisplayInfo: {
        processingMessage: "Processing Ping transaction",
        errorMessage: "An error has occured during Ping",
        successMessage: "Ping transaction successful",
      },
      redirectAfterSign: false,
    });
    console.log({ sessionId });
  };

the log of sessionId always is null, what did I comment to you after your answer, i try with the example "ping" of dapp-template

Thank you for the details 🙏

Do you think you can downgrade the erdjs reference, until dapp-template is updated to use erdjs v10?

Both dapp-template and dapp-core were upgraded to erdjs v10, I will close this issue. If the issue still persists, feel free to re-open
