All Errors

MySQL error 29 (EE_FILENOTFOUND) occurs when the database server cannot locate a required file. This commonly happens with LOAD DATA INFILE operations, when accessing database table files, or due to file permission restrictions.

This error occurs when attempting database operations after the MongoDB client connection has been closed or when the topology (internal connection manager) was terminated. The most common cause is closing the client prematurely or attempting operations on a stale connection.

MySQL ERROR 1365 occurs when a query divides by zero, halting execution. Fix it using NULLIF(), CASE statements, or filtering with WHERE clauses to handle zero denominators safely.

The MOVED error occurs in Redis Cluster when a client connects to the wrong node for a given hash slot. The cluster returns this error with the correct node address, requiring the client to redirect the query or update its topology knowledge.

An encoding mismatch occurs when the server encoding, client encoding, or database collation settings do not align, preventing proper character handling and data transfer. Resolve by standardizing encodings to UTF-8 across your PostgreSQL configuration.

The Prisma P2025 error occurs when you try to update, delete, or connect to records that don't exist in your database. This commonly happens with delete operations ("Record to delete does not exist"), update operations ("Record to update not found"), or nested relation connects that reference missing records.

DynamoDB returns LimitExceededException when you exceed the concurrent control plane operation limits. This error occurs when trying to create, update, or delete more than 10 tables simultaneously, or when the cumulative total of tables and indexes in CREATING, UPDATING, or DELETING state exceeds 500.

This error occurs when attempting to create a new snapshot in Elasticsearch while another snapshot or restore operation is already running on the same repository. Elasticsearch enforces snapshot serialization per repository to maintain data consistency and prevent conflicts in the repository state.

Supabase rejects requests with a bad_jwt error when the JWT token in the Authorization header cannot be validated. This typically happens when using the wrong token type, an expired token, or a malformed JWT structure. This guide shows how to identify and fix JWT validation issues.

PostgreSQL detects corrupted data when checksums are enabled. Recover by using failover replicas, replaying WAL from backups, or zeroing damaged pages with appropriate settings.

The Prisma P2019 error occurs when there is a problem with the input provided to a Prisma Client query. This generic input validation error indicates that query parameters or data don't meet expected requirements, such as missing required fields, incorrect data types, or invalid JSON path filters.

Supabase responds with "not_admin: User is not an admin" when you attempt to call an admin-only operation using a regular user JWT instead of a service_role key. Admin operations like createUser, updateUserById, and deleteUser require elevated privileges that bypass Row Level Security and can only be executed on trusted servers with the service_role key.

The CursorNotFound error occurs when MongoDB cannot locate a cursor that your application is trying to access. This typically happens when a cursor times out after 10 minutes of inactivity, when processing large result sets slowly, or in load-balanced sharded cluster configurations. Understanding cursor lifecycle and timeout management is essential for handling large datasets.

PostgreSQL index corruption causes queries to return incorrect results or fail. Rebuild the corrupted index using REINDEX to restore normal database operations.

This MySQL client error occurs when the client library cannot load the required character set definition files from disk. The error typically indicates that the character set files are missing, corrupted, or inaccessible, often due to incomplete MySQL installation, missing /usr/share/mysql/charsets directory, or incorrect file permissions.

MongoDB raises UnknownTransactionCommitResult when a transaction commit operation encounters a network error, server selection error, or write concern timeout, leaving the commit state uncertain. This error label signals that retrying the commit may succeed, as the transaction might have actually committed despite the error.

This Firebase Cloud Messaging error occurs when the message payload structure is invalid, contains incorrect JSON formatting, uses reserved keywords, or has incompatible field types. The error prevents message delivery until the payload structure is corrected.

This MySQL client error occurs when attempting to execute prepared statement operations on a statement that has not been properly initialized or prepared. The error indicates that statement handler functions are being called in the wrong order or on an invalid statement object.

Firebase returns a service unavailable error when it cannot process your request, typically due to temporary service disruptions, network connectivity issues, or device offline conditions with no cached data. This is usually a transient error that can be resolved by implementing retry logic with exponential backoff.

This error occurs when SQLite cannot access a database file or directory due to insufficient file system permissions. Common causes include incorrect ownership, restrictive file modes, or attempting to write to read-only locations.
