Fix Drupal Cache Context Vary Errors

You will learn to fix drupal cache context vary errors

The Problem

The drupal cache context vary pattern is frequently misapplied in smart contract and dapp development, leading to vulnerabilities, gas inefficiencies, or logic errors. This guide shows the correct implementation and common pitfalls to avoid.

Quick Fix

Wrong

$build['#cache']['contexts'][] = 'url'; // Varies by URL

Correct but may create many cache entries.

Right

$build['#cache']['contexts'] = ['url.path', 'user.permissions'];

Specific contexts with minimal cache variation.

Prevention

• Use specific path contexts instead of full URL
• Avoid user context for public content
