Fix Drupal Block Cache Tag Errors

You will learn to fix drupal block cache tag errors

The Problem

The drupal block cache tag 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

public function build() { return ['#markup' => $this->getData()]; }

No cache tags. Block shows stale data.

Right

public function getCacheTags() { return ['node_list', 'config:my_settings']; }

Cache invalidated when nodes or settings change.

Prevention

• Add relevant cache tags for automatic invalidation
• Use max-age 0 for highly dynamic content
