Function to debug paths in AWS lambda (but not only)

index.js

const fs = require('fs');
const path = require('path');

function debugPath(targetPath) {
    console.log(`Debugging path: ${targetPath}`);
    console.log('='.repeat(50));
    
    const segments = targetPath.split('/').filter(segment => segment !== '');
    let currentPath = '';
    
    // Start from root if path is absolute
    if (targetPath.startsWith('/')) {
        currentPath = '/';
        console.log(`Root directory (/): exists`);
    }
    
    for (let i = 0; i < segments.length; i++) {
        currentPath = path.join(currentPath, segments[i]);
        
        try {
            const stats = fs.statSync(currentPath);
            console.log(`✓ ${currentPath}: ${stats.isDirectory() ? 'directory' : 'file'}`);
            
            if (stats.isDirectory()) {
                try {
                    const contents = fs.readdirSync(currentPath);
                    console.log(`  Contents: [${contents.join(', ')}]`);
                } catch (err) {
                    console.log(`  Cannot read directory: ${err.message}`);
                }
            }
        } catch (err) {
            console.log(`✗ ${currentPath}: ${err.code} - ${err.message}`);
            break;
        }
        console.log('-'.repeat(30));
    }
}

// Debug the specific path from your error
debugPath('/opt/nodejs/your/path');
