SendRequestAndWaitForReceiptAsync Method Hangs Indefinitely Without Returning transactionReceipt

[marcelocamargosjr]

Description:

The SendRequestAndWaitForReceiptAsync method in the following code is hanging indefinitely and does not return the transactionReceipt.

Code Snippet:

var mintFunction = new MintWithCustomerIdAndTransactionIdFunction
{
    To = mint.RecipientAddress,
    Amount = new BigInteger(mint.Amount * (decimal)Math.Pow(10, 18)),
    CustomerId = mint.Transaction.CustomerId.ToString(),
    TransactionId = mint.Transaction.Id.ToString()
};

var transactionReceipt = await contractHandler.SendRequestAndWaitForReceiptAsync(mintFunction);

Steps to Reproduce:

1. Execute the above code in the project.
2. Observe that the call to SendRequestAndWaitForReceiptAsync does not return and hangs indefinitely.

Expected Behavior:

The SendRequestAndWaitForReceiptAsync method should return a transactionReceipt after the transaction is processed.

Actual Behavior:

The SendRequestAndWaitForReceiptAsync method hangs indefinitely and does not return a transactionReceipt.

Environment:

• .NET version: net6.0
• Nethereum version: 4.20.0

Possible Cause:

This issue might be related to network connectivity, incorrect contract address, or issues with the blockchain node. Further investigation is required to pinpoint the exact cause.

Suggested Solutions:

1. Verify the network connectivity and ensure that the blockchain node is reachable.
2. Check the contract address and other parameters passed to the mintFunction.
3. Consider adding a timeout to the SendRequestAndWaitForReceiptAsync method call to avoid indefinite hanging.
4. Enable logging to capture more details about the transaction process.

Additional Information:

Any additional information or logs that can help in diagnosing the issue.

according to your MintWithCustomerIdAndTransactionIdFunction it's a FunctionMessage which derives from ContractMessageBase. If You don't set required properties such Nonce it will never receive receipt.
In your request var transactionReceipt = await contractHandler.SendRequestAndWaitForReceiptAsync(mintFunction); you didn't set cancellation token with any timeout wich is an optional parameter when calling this (Task<TransactionReceipt> SendRequestAndWaitForReceiptAsync(string contractAddress, TContractMessage functionMessage, CancellationToken cancellationToken);)
