All Errors

Every MongoDB write concern is guarded by a timeout. When a write needs acknowledgements from more than the primary, the driver waits for those replicas but eventually raises "WriteConcernError: waiting for replication timed out" if the replicas cannot confirm the write before the configured wtimeout expires.

MySQL ERROR 1021 occurs when the server runs out of disk space while writing data or temporary files. The server will pause operations and wait for space to become available. Fix it by freeing disk space, managing binary logs, redirecting the temp directory, or expanding storage.

PostgreSQL throws 2200M (invalid_xml_document) when libxml2 rejects the payload passed to XMLPARSE, XMLTABLE, XML functions, or an xml column insert because the text is not a well-formed XML document. The parser wants a single root node and complete tag structure, so missing roots, stray text nodes, or bad syntax cause the query to fail before the server ever stores or evaluates the value.

This TypeScript error occurs when attempting to iterate over a value that does not implement the iterable protocol, such as using for...of on non-array types or union types containing non-iterable values.

This TypeScript error occurs when you try to assign a value that might be undefined to a variable expecting only a string type. It happens most often with optional properties, function parameters, or when strictNullChecks is enabled.

This error occurs when TypeScript's type narrowing eliminates all possible types from a union, leaving the impossible "never" type. It typically happens with typeof checks that exclude all valid type options.

This error occurs when a generic type parameter has constraints that contradict each other or when trying to use a constrained type in ways that conflict with its defined boundaries.

This error occurs when TypeScript cannot verify that a value matches an inferred type within a conditional type. It typically happens when using the infer keyword in complex conditional types where type narrowing is insufficient.

This TypeScript error occurs when you try to assign a number value to a variable, parameter, or property that expects a string type. Fix it by using type conversion, union types, or correcting the type declaration.

This error occurs when TypeScript infers a variable as the never type (representing impossible values) but you try to assign or use it where a string is expected, commonly from untyped empty arrays or over-narrowed type guards.

This error occurs when Vite's Rollup bundler cannot locate an imported module during the production build process. It typically indicates incorrect file paths, missing dependencies, or misconfigured path aliases.

This warning occurs when Vite encounters a race condition during dependency pre-bundling, causing source map files to be temporarily unavailable. While it appears in DevTools, it typically does not affect application functionality.

This TypeScript error occurs when the compiler cannot locate a module or its type definitions in your Vite project, often due to incorrect tsconfig.json settings or missing type packages.

This error occurs when Vite cannot establish a WebSocket connection for Hot Module Replacement, preventing live updates during development. It typically happens with proxy servers, Docker environments, or incorrect network configurations.

This error occurs when you attempt to use a generic type in a function without properly declaring its type parameters. TypeScript requires that all generic type parameters be declared in angle brackets before they can be used in function signatures or implementations.

This TypeScript configuration error occurs when useDefineForClassFields conflicts with your target setting. The option defaults to true for ES2022+ but false for older targets, causing compatibility issues when explicitly mismatched.

TypeScript throws this error when type recursion or nesting exceeds internal depth limits (50-500 instantiations). This commonly happens with deeply nested generic types, recursive type definitions, or complex type compositions.

This error occurs when TypeScript cannot guarantee that a type is iterable, typically when targeting ES5/ES3 without proper configuration. Enable downlevelIteration in tsconfig.json to fix it.

This TypeScript error occurs when you declare a generic type parameter on a function but never actually use it to relate types in the function parameters or return type. The type parameter serves no purpose and should either be removed or properly utilized.

This TypeScript compiler warning occurs when you declare a generic type parameter but don't reference it in the function signature, return type, or implementation. Fix it by using the parameter, removing it, or prefixing with underscore.
