All Errors

This error occurs when Node.js fails to generate RSA key pairs using the crypto module. It typically results from memory constraints, invalid parameters, system resource limits, or OpenSSL library issues.

ESLint warning from the exhaustive-deps rule indicating that a variable, prop, or state value referenced inside useCallback is not included in its dependency array. This can lead to stale closures and bugs where the callback uses outdated values.

PostgreSQL error 42883 occurs when you try to use an operator with incompatible data types. This commonly happens when comparing strings with integers or using operators on unsupported type combinations. Explicit type casting resolves this issue.

The DocumentNotFoundError occurs when MongoDB cannot find any documents matching your query criteria. This typically happens when querying with incorrect filters, accessing deleted documents, or working with empty collections. Understanding query patterns and validation can help prevent this error.

This error occurs when you pass an unsupported or invalid encoding name to a Node.js readable stream's setEncoding() method. Common causes include typos in encoding names, using encodings that aren't built-in to Node.js, or specifying an encoding that doesn't match your data format.

This error occurs when Node.js cannot locate the TLS certificate files required to establish a secure connection. It typically indicates missing, misconfigured, or inaccessible certificate paths in your HTTPS/TLS server setup.

PostgreSQL fails to start when SSL is enabled but the server certificate file (server.crt) is missing, unreadable, or incorrectly configured. This error prevents any SSL connections from being established. Ensure the certificate file exists in the correct location with proper permissions.

Redis returns "ERR BGREWRITEAOF scheduled when RDB save in progress" when you try to start an AOF rewrite while a background RDB snapshot is already running. This prevents simultaneous persistence operations that could conflict or overload memory/disk. Wait for the current RDB save to finish, check persistence settings, or manually schedule AOF rewrites during low‑traffic periods.

This error occurs when stream operations attempt to access the length property of a null chunk, typically when null values are written to streams or when stream buffers contain null entries.

This Foreign Data Wrapper error occurs when a query needs a dynamic parameter value at runtime but the FDW cannot obtain or convert it. Common with timestamp functions, date conversions, or runtime-evaluated expressions in queries against foreign tables.

PostgreSQL does not allow changing column data types in views using CREATE OR REPLACE VIEW. When the underlying table columns change type, the view definition becomes invalid. Drop and recreate the view with matching column types.

This error occurs when SQLite's Write-Ahead Logging (WAL) mode database is being recovered by another process, preventing concurrent access. It's a specific busy error that happens during WAL checkpoint or recovery operations when multiple processes attempt to access the database simultaneously.

This error occurs when Node.js attempts to open a file with an invalid path argument. Common causes include malformed file paths, invalid characters in filenames (especially on Windows), and filesystem issues on external drives.

This error occurs when Firebase Cloud Messaging rejects a registration token because it is malformed, corrupted, expired, or doesn't match the expected FCM token format. The fix involves validating token generation, ensuring tokens aren't modified during transmission, and removing invalid tokens from your database.

This error occurs when you call the currval() function before calling nextval() on a sequence in the current PostgreSQL session. The currval() function returns the last value generated by nextval() within the same session, and it requires that nextval() has been called at least once first.

The SQLITE_INTERNAL error indicates an internal malfunction within the SQLite engine itself, often caused by bugs in SQLite, custom extensions, or Virtual File System (VFS) implementations. This error suggests a serious problem that requires investigation beyond typical application-level fixes.

This error occurs when using a RANGE frame in a window function with a temporal ORDER BY column, but the frame bounds do not use INTERVAL syntax. MySQL requires INTERVAL expressions like "INTERVAL 5 DAY PRECEDING" for temporal columns.

This error occurs when SQLite cannot upgrade a read transaction to a write transaction due to snapshot isolation conflicts. It happens when a transaction starts in read mode, but later tries to write while other transactions are accessing the same data snapshot.

This SQLite I/O error occurs when the database engine encounters a disk I/O failure during read operations, typically indicating hardware issues, filesystem problems, or permission errors. It's a critical error that prevents SQLite from reading database files and requires immediate investigation to prevent data loss.

PostgreSQL raises error 38000 when an external routine (such as a C function, external procedure, or foreign data wrapper function) encounters an exception during execution. This occurs when external code linked with PostgreSQL fails, throws an exception, or violates PostgreSQL's execution environment constraints.
