Error while confirming transaction in Trust Wallet: “Receipt type undefined – in Trust Wallet”

When attempting to confirm a transaction on a digital wallet such as Trust Wallet, a user may encounter the error message “Receipt type undefined – in Trust Wallet”. This error can be frustrating and requires immediate attention.

The error occurs because the ConfirmTransaction function, which the wallet uses to verify transactions, requires one of four specific data types for its arguments. However, it appears that the received type is not defined as one of these options.

Understanding Data Types

To resolve this issue, let’s take a closer look at the required data types:

  • String: A string is a sequence of characters that represents text.
  • Buffer

    Metamask: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined -in Trustwallet

    : Buffer is an array-like object used to represent a buffer of bytes in memory.

  • Array

    : An array is an ordered collection of elements.

  • Array-like object (e.g. Uint8Array): An array-like object such as `Uint8Array'' represents a raw byte array.

Possible causes and solutions

Based on the error message, the issue appears to be in how the wallet received the transaction data as an argument to theConfirmTransactionfunction. Here are some possible causes and solutions:

  • Invalid or missing argument: The wallet may not have provided one of the required data types (string, buffer, array) as an argument.
  • Incorrect buffer representation: If the data received is not in a valid buffer format (e.g. it is not a Uint8Array), the wallet may receive an incorrect value for theTransaction'' object.

To troubleshoot and resolve this issue:

  • Verify that the transaction data being sent to the wallet is properly formatted, either as a string, buffer, array, or array-like object.
  • Check the wallet documentation to make sure it supports the required data types for transaction confirmation.
  • If possible, inspect the transaction data in detail to make sure it is formatted correctly.

Corrected Code Example

If you are using the Trust Wallet API, here is an updated example that shows how to properly pass a string as an argument:

const tx = {
id: '1234567890',
from: 'your_wallet_address',
to: 'recipient_address',
value: 10.00,
};
const confirmTransaction = await trustWallet.confirmTransaction(tx);
// Confirm the transaction with the received data

In this example, we have assumed that txis an object representing the transaction. The key values ​​areid,from, andto. We also assume that there is some other value forvalue.

By following these steps and checking your wallet documentation, you should be able to resolve the errorReceived type undefined – in Trust wallet` when trying to confirm transactions in your digital wallet.
