Ethereum: Solve the error “Invalid Bigber Value” with euters.js
In collaboration with Ethereum contracts, especially with Ethers.js, meeting the “Invalid Bigber” error can be disappointing. This error usually occurs when you try to call a function of a contract for Ethereum, which is expected to be Bignumber.
Problem: Invalid BIGNUMBER value error
In this article, we look at what causes the “invalid Bignumber” error and offers solutions to resolve it in Ethers.js applications.
What is Bignerum?
Bignumber is a JavaScript directory used to depict integers with arbitrary accuracy. It provides classes such as Bignumer, Bigint and Corporal, which support a large number of operations.
The reason for the error
When you create a copy “Bignumer”, it essentially creates endless accuracy. However, if you transfer this value as an argument for a contractual function, you can create problems if:
- The entrance is not properly formatted
: If Bignumber is created by a string or other incompatible format, it may not be in the expected condition.
- Bignumber’s copy is modified after creation
: if the Bignumber copy changes from the outside (for example, using the JavaScript code), the internal state will change unexpectedly, leading to incorrect calculations.
to solve the error
To resolve the BIGNUMBER Invalid Value, you can try the following:
Option 1: Rate the input and create a new copy of Bignumber
Before we invite a contract for a copy of Bignumber:
`Javascript
const mnemonic = 'your_mnemnic';
Portfolio = euters.wallet.frommnemonic (Mnemonic);
Signing = portfolio.connect (service provider);
// Check the Bignumber's specimen from outside -e
Console.log (Signer.Address); // Organize the instance to remain unchanged
CONST Routeraddress = '0x ...'; // Replace contract address
Routerinstance = New Euters.conract (Routeraddress, ...
Option 2: Use a directory like “Ether.js-Bignumber” or @nomiclabs/euters -abi"
To avoid Bignumber specimens to be modified externally:
Javascript
Imports of Bignumber from "BIGN NUMBER";
const mnemonic = 'your_mnemnic';
Portfolio = euters.wallet.frommnemonic (Mnemonic);
Signing = portfolio.connect (service provider);
CONST Routeraddress = '0x ...'; // Replace contract address
// Use the Bignumber Library to create a new copy that remains unchanged
Const Bignumer = new Bignumber ('1'); // Create a copy of the Bign Pump
Routerinstance = new euters.conract (Routeraddress, {
Methods: {
Myfunction (Bignumber): Promise
}
});
Following these steps or using the above libraries, you should be able to resolve the “invalid value of your jacket value” and continue to work with Ethers.js applications.
