All Errors

Redis logs `ERR CONFIG REWRITE failed: Permission denied` when the CONFIG REWRITE command cannot write changes back to the configuration file. This happens due to restrictive file or directory permissions, SELinux policies, systemd service hardening, or incorrect file ownership. This guide covers diagnosing permission issues, fixing file ownership and directory permissions, resolving SELinux conflicts, and updating systemd service files.

The "invalid regular expression" error (code 2201B) occurs when PostgreSQL encounters malformed regex syntax. Common causes include unescaped special characters, unbalanced parentheses, invalid escape sequences, or PCRE-specific syntax incompatible with PostgreSQL's POSIX regex engine.

This Fastify error occurs when your route handler or hook attempts to send a response multiple times for the same HTTP request. Fastify prevents duplicate responses, which would cause protocol violations and unpredictable client behavior.

This error occurs when your build tool or development server cannot locate the React library in your project. It typically happens when React is not installed, node_modules is missing or corrupted, or your package.json dependencies are incomplete. Resolving this requires ensuring React is properly installed and your project's dependency tree is intact.

This MySQL error occurs when data being inserted or updated violates a CHECK constraint defined on a table. CHECK constraints enforce data integrity rules at the database level, ensuring values meet specific conditions. The error indicates that one or more rows fail to satisfy the constraint condition, preventing the operation from completing.

This Firebase Storage error occurs when the file checksum calculated on the client does not match the checksum validated by the server during upload. This indicates data corruption during transmission, typically caused by network interruptions or unstable connections. The solution is to retry the upload with proper error handling.

This ESLint warning appears when a React component lacks a displayName property, making it difficult to identify in React DevTools and error stack traces. It commonly occurs with components wrapped in React.memo(), React.forwardRef(), or higher-order components (HOCs).

This error occurs when attempting to import a module using default import syntax, but the module only exports named exports. The mismatch between import and export styles causes TypeScript or your bundler to fail.

This warning occurs when rendering an array of elements without assigning a unique "key" prop to each element. Keys help React identify which items have changed, been added, or removed, enabling efficient updates and preventing state mismatches.

React (and bundlers that target it) throws this error when you import a component as a default export but the module only exposes named exports. Align the import/export style or re-export the named symbol as the default so React actually receives the component it expects.

React bundles sometimes leave Node-style `module` references inside browser chunks, so the runtime throws `ReferenceError: module is not defined`. Make sure every file and dependency emits ES module syntax or that your bundler rewrites CommonJS APIs before shipping the code.

This warning occurs when a React component returns an invalid value instead of a valid React element, null, or undefined. React expects components to return JSX elements, but sometimes components accidentally return functions, promises, or forget the return statement entirely.

The Prisma P5011 error occurs when your application exceeds the request rate limits of Prisma Accelerate. This typically happens during traffic spikes, high-concurrency scenarios, or when implementing aggressive retry logic without proper backoff strategies. The fix involves implementing rate limiting, adding exponential backoff, and optimizing your query patterns.

This error occurs when a SQL/JSON path expression tries to access an array element on non-array data. Resolve it by verifying your JSON structure matches the path expression and using jsonb_typeof() to check data types.

The "sms_send_failed: Sending SMS failed" error occurs when Supabase Auth cannot send SMS messages for phone authentication or OTP verification. This typically happens due to misconfigured SMS provider settings, rate limiting, invalid phone numbers, or insufficient credits with the SMS service provider.

The PostgreSQL error "42P10: invalid_column_reference" occurs when a SQL statement references a column in an invalid context, such as using a column that doesn't exist in the current scope or referencing it incorrectly in subqueries, joins, or window functions. This syntax error prevents query execution and requires correcting the column references.

This error occurs when you attempt to insert or update a row with a primary key value that already exists in the table. SQLite enforces primary key uniqueness strictly, rejecting duplicate key values to maintain data integrity and ensure each row is uniquely identifiable.

The Prisma P5007 error occurs when authentication fails to Prisma Accelerate due to an invalid or missing API key in your connection string. This error prevents your application from connecting to the database through Accelerate's managed proxy service. The fix involves verifying your API key, checking the connection string format, and ensuring your Accelerate project is enabled.

This error occurs when Supabase cannot find a valid refresh token during authentication. Refresh tokens are used to obtain new access tokens without requiring users to re-enter credentials. The fix typically involves checking token storage, session management, and authentication flow configuration.

The "anonymous_provider_disabled: Anonymous sign-ins are disabled" error occurs when Supabase Auth attempts anonymous authentication but anonymous sign-ins are not enabled in the project settings. This prevents users from creating temporary anonymous accounts until anonymous authentication is properly configured and enabled.
