Error in the recovery of transactions on Solana with server without server
As a developer creating server -free functions for Solana, you can meet a common error when you try to recover the transactions. In this article, we will immerse ourselves in the details of the error and provide advice on how to resolve it.
The error
The error message “Typerror: S.Wallet is not a manufacturer” indicates that there is a problem with the way you access the object Wallet in your server without function code. The variable S 'probably represents an SDK Solana instance, which contains various utility and functions to interact with the blockchain.
In the context of the recovery of transactions on Solana, the "wallet" object is used to obtain a private key or an account address that can be used to interact with the blockchain. However, when you call "S.Wallet", it returns an error because "S.Wallet" is not a manufacturer.
Why does it happen?
There are several reasons why this error could occur:
- Incorrect SDK version: Make sure you use the latest version of the SDK Solana which supports your server-free excitement (for example,
Solana / Customer-Jsfor NODE.JS).
- missing outbuildings: Make sure all the required dependencies, including
s, are correctly installed and imported into your code.
- Incorrect function order: The error can occur when you call a function before importing the SDK Solana.
Solution
To solve this problem, follow these steps:
- Check your SDK version: Check that you use the latest version of the SDK Solana for your server -free excitement.
- Imported the Solana dependencies correctly: make sure you have correctly imported the outbuildings required in your code.
- Check the order calls: Make sure you do not call a function before importing the SDK Solana.
Here is an example of how to modify your code to solve the problem:
Javascript
Const {customer} = require ('@ solana / web3.js');
Fetchtransactions asynchronous function () {
Const customer = new customer ({
Key room: "path / to / your / secret",
});
to try {
// Repunction of transactions
Const txs = wait customer. Fetchtransactions ();
// Treat the recovered transactions
console.log (TXS);
} Catch (error) {
Console.error (error);
}
}
fetchtransactions ();
'
In this example, we import the classCustomer ‘of the SDK Solana and create an instance using the secret key provided. We then call the “Fetchtransactions” function to recover the recovered transactions.
Conclusion
To resolve the error “Typeerror: S.WALLET is not a manufacturer” when recovering transactions on Solana with server-free functions, make sure you use the latest version of the SDK Solana and that you have imported correctly All the required dependencies. Check that your functional order order is correct and plan to add journalization or debugging instructions to help identify any potential problem.
Additional advice
- Make sure you manage errors properly in your server without a server, as they can provide valuable information on all the problems that may arise.
- Consider using a recording library like `Winston ‘or” Log4js “to follow errors and exceptions for better error analysis.
- If you create a complex application with several outbuildings, consider using a dependent management tool such as “NPM-Dev-Dependces” or “Yarn Workspaces” to make sure that all the required libraries are properly installed.
