Mastering the debug-action-cache : A Guide to Troubleshooting Remote Build Execution

Combine this with debug-action-cache logs from the workflow run (download the raw logs). Match the cacheKey from the API with the Cache restored from key in the logs. If the last_accessed_at is older than your run, your restore key is wrong. debug-action-cache
