All Errors

A hydration mismatch occurs when the HTML rendered on the server differs from what React renders on the client during hydration. This causes React to fail to properly attach to existing markup and can lead to missing event listeners, state inconsistencies, and unexpected behavior. Understanding the root cause and using the right solution prevents this critical SSR issue.

This admission error occurs when ResourceQuota or LimitRange requires containers to specify resource requests. Fix it by adding explicit requests.cpu and requests.memory to your container spec.

This error occurs when a Kubernetes Deployment fails to reach its desired state within progressDeadlineSeconds (default 10 minutes). Pods may be stuck due to image pull failures, scheduling issues, or resource constraints.

This error occurs when npm update can't complete successfully. Usually caused by version conflicts, registry issues, or corrupted package state.

This error occurs when npm can't flatten the dependency tree to remove duplicates. Usually caused by version conflicts or peer dependency issues that prevent deduplication.

This error occurs when JavaScript code attempts to access a variable that hasn't been declared, is out of scope, or was misspelled. It's one of the most common errors in Node.js and typically indicates an undeclared variable reference.

DeadlineExceeded occurs when a Kubernetes Job exceeds the time limit specified by activeDeadlineSeconds. Kubernetes terminates all running Pods and marks the Job as failed.

The npm SIGHUP error occurs when the controlling terminal is closed or disconnected, typically during SSH sessions, remote deployments, or when terminal windows are closed while npm is running.

This Windows error indicates that Node.js is not in your system PATH, preventing npm and node commands from running. The fix involves adding Node.js to your PATH environment variable or reinstalling Node.js.

This error occurs when Node.js cannot find a required module because dependencies haven't been installed. Run npm install to download all dependencies listed in package.json.

This TypeScript error occurs when you call a function with more arguments than it expects. The compiler is enforcing function signature matching to prevent bugs from passing unnecessary or incorrect arguments.

KubeletNotReady occurs when the kubelet service on a worker node becomes unhealthy or stops communicating with the control plane. This is often caused by container runtime failures, certificate issues, or systemd service problems.

This warning appears on Linux and Windows because fsevents is a macOS-only file watching library. This is completely safe to ignore—npm correctly skips the dependency, and your application works normally without it.

HTTP requests fail when they exceed the configured timeout threshold, typically defaulting to 30 seconds. This occurs when the remote server is slow to respond, network connections are unstable, or response payloads are too large to process within the timeout window.

This error occurs when Node.js attempts to import a directory but cannot locate an index.js file or a valid entry point specified in package.json. It typically happens when directory imports rely on implicit index file resolution.

The 'cb() never called' error indicates npm's internal callback function failed to execute during installation. The fix typically involves clearing the npm cache, checking network connectivity, or updating npm/Node.js versions.

The 'npm ERR! canceled' error occurs when npm abruptly terminates an operation, typically due to user interruption, network timeout, cache corruption, or missing packages in non-interactive environments.

DiskPressure indicates a node is running critically low on available disk space. The kubelet stops scheduling new pods and begins evicting existing pods to reclaim disk space.

The EMFILE error occurs when npm exceeds the operating system's file descriptor limit, typically during large installs or builds. The fix involves increasing the ulimit or using graceful-fs to handle file operations more efficiently.

Navigation errors in Next.js pages directory typically occur when using the wrong useRouter import or attempting to use App Router features in pages. This happens because Next.js has two routing systems with different APIs and imports, and mixing them causes runtime failures.
