All Errors

This error occurs when a Redis cluster becomes unavailable due to node failures or missing hash slot coverage. The cluster stops accepting requests until all hash slots are covered again by available nodes.

This TypeScript error occurs when a method decorator returns an invalid type. Method decorators must either return void (for side effects) or a PropertyDescriptor to replace the original method. The error helps ensure type safety and proper runtime behavior of decorated methods.

This TypeScript compilation error occurs when upgrading RTK Query to version 2.4.0 or later, where internal type definitions for tag descriptions cause compatibility issues even when not using tags in your API definitions.

This error occurs when a MySQL window function frame specification uses UNBOUNDED PRECEDING as the frame end boundary. Window frames must follow logical ordering where the frame start cannot occur later than the frame end in the dataset.

This error occurs when Elasticsearch encounters a document with fields not defined in the index mapping, and the mapping is configured with "dynamic": "strict". Elasticsearch rejects the document to prevent schema drift and ensure data consistency. The fix involves updating your mapping to allow dynamic fields or explicitly defining all expected fields.

Redis returned 'ERR unknown command' when you tried to execute a Redis command. This error means the server doesn't recognize the command you sent, usually due to a typo, version mismatch, connecting to the wrong Redis instance, or missing Redis modules.

This error occurs when attempting to link an OAuth identity to an existing user via linkIdentity() while the manual linking feature is disabled in your Supabase project settings. Manual linking must be explicitly enabled for security reasons.

SQLSTATE 22009 occurs when PostgreSQL encounters an invalid time zone offset or displacement value. This error typically appears when working with time zone-aware timestamps, interval arithmetic, or when converting between time zones with malformed offset values.

This error occurs when using React Testing Library's queryBy* methods with async assertions like waitFor or findBy*. queryBy* queries are designed for synchronous checks and return null when elements aren't found, while findBy* and getBy* queries handle async operations properly. Understanding the difference between query types prevents this common testing mistake.

This error occurs when PostgreSQL rejects a login attempt due to incorrect credentials, misconfigured authentication settings, or a missing password. Common causes include wrong password, incorrect pg_hba.conf authentication method, or users created without passwords.

Supabase Auth rejects an email address during signup or authentication due to format validation rules. This typically occurs when the email format violates Supabase's validation requirements, which may be stricter than standard RFC 5322 specifications.

This TypeScript error occurs when you try to import a module using default import syntax (import X from "module"), but the module only exports named exports. The fix involves changing your import syntax to use named imports or modifying the module to include a default export.

This TypeScript error occurs when trying to import a default export from a module that doesn't have one. The module might use named exports instead, or the export configuration may be incorrect. Fixes include using named imports, checking module's export structure, or configuring esModuleInterop.

This error occurs when PostgreSQL cannot determine whether a transaction was committed or rolled back due to a connection loss. It typically indicates a network disruption between your application and the database server.

This PostgreSQL error occurs when attempting to insert a duplicate value into a column with a unique constraint in your Supabase database. The constraint could be a primary key, unique index, or explicitly defined unique column.

This TypeScript configuration error occurs when you try to use the modern 'esnext' module system with legacy JavaScript targets (ES3 or ES5). The esnext module format requires modern JavaScript features that aren't available in older ECMAScript versions. To fix this, either upgrade your target to ES2015+ or switch to a compatible module system like CommonJS.

This TypeScript error occurs when you declare a namespace without providing a name. Namespaces help organize code into logical groups and prevent naming collisions. The fix involves adding a valid identifier after the "namespace" keyword.

This error occurs when you attempt to connect to PostgreSQL while it is still initializing or recovering from an unexpected shutdown. Typically, waiting for the startup process to complete or restarting the database service resolves the issue.

The ioredis 'Command timed out' error occurs when a Redis command fails to return a response within the configured timeout period. This typically indicates network issues, slow Redis operations, or insufficient timeout configuration.

This TypeScript error occurs when you have multiple namespace declarations with conflicting structures. It typically happens when merging namespaces from different files or when type definitions have incompatible members. The fix involves ensuring consistent namespace structure across all declarations.
