Solana: How to fix sb.AnchorUtils.loadEnv() wrong keyfile path?

''bash

./target/deploy/

|- .env

|- ... (other files)

Note the dot (.) at the end of.env, which is incorrect. It should be relative to the current working directory or the specified base directory.

Solution: Update the key file path
To fix this, you need to update the key file path to point directly to thekey'' file:

javascript

const { keypair, connection, application } = await sb.AnchorUtils.loadEnv('./target/deploy/.env');

Make sure your .env file is in a relative path that is specified correctly. In this case, you are already using./target/deploy/, so the path should be correct.

Additional Tips
Be careful using absolute paths in production environments to avoid security issues.
Consider using environment variables directly instead of loading them from files:

typescript

const { keypair, connection } = await sb.AnchorUtils.loadEnv();

This method eliminates the need for file paths and makes your code more secure.

Use Case Example
Here is a detailed example that shows how to solve the problem:

typescript

import { AnchorUtils } from 'inchor';

import sb from '@subql/sb';

import { anchorUtil } from './anchor-utils';

const accountAddress = 'your account address';

const secret = 'your password';

const networkName = 'mainnet';

// Set the node URL, cluster name, and network type

const nodeUrl = '

const clusterName = 'cluster name';

const networkType = 'mainnet';

try {

// Load environment variables

const { keypair, connection } = await anchorUtil.loadEnv();

// Use the loaded environment variables

const program = new sb.Program(networkName, nodeUrl, clusterName);

// Perform some operations on the account and secret...

} catch (error) {

console.error(error);
