Post job cleanup. Cache saved successfully: false – Cache size limit exceeded (2.1 GB > 2 GB)
: Caches are typically isolated by operating system. A cache created on ubuntu-latest will not be available for a windows-latest runner.
To maximize the benefits of debug-action-cache , follow these best practices:
: If the job finishes successfully after a cache miss, the system compresses the targeted directories and uploads them as a new cache entry associated with the primary key. Core Strategies to Debug Action Caches debug-action-cache
- name: Cache Node Modules uses: actions/cache@v4 env: CACHE_DEBUG: true with: path: node_modules key: $ runner.os -node-$ hashFiles('package-lock.json')
Look for changing environment variables (like PATH or timestamps) that are leaking into the action environment and invalidating the cache. Best Practices for Healthy Action Caching

Exporting cache hierarchy as a directed acyclic graph (DAG) to identify which dependency layer caused the invalidation. 4. Implementation Case Study
In this 2,500+ word guide, we will dissect the anatomy of action caching, explore why debugging is necessary, and provide a step-by-step playbook to master debug-action-cache .
By caching the results of these actions, developers can avoid redundant computations, reducing build times and improving overall efficiency. The debug-action-cache acts as a transparent layer between the development environment and the CI/CD pipeline, seamlessly integrating into existing workflows. To maximize the benefits of debug-action-cache , follow
The Debug Action Cache is a mechanism designed to store and retrieve the results of expensive computations, reducing the need for redundant calculations and improving overall performance. This report provides an analysis of the Debug Action Cache, highlighting its functionality, benefits, and potential issues.
restore-keys: | $ runner.os -node-$ hashFiles('package-lock.json') # exact same hash $ runner.os -node- # any older node cache – use as last resort
Run the build a second time after a minor change or on a different machine.
