All Errors

This error occurs when a PostgreSQL database's character encoding does not match the LC_CTYPE and LC_COLLATE locale settings. PostgreSQL requires that database encodings are compatible with the system locale. For non-C/POSIX locales, only one character set will work correctly with each locale.

PostgreSQL system errors (error code 58000) indicate unforeseen issues external to the database itself, such as hardware failures, disk problems, or file system corruption. Diagnosing requires checking logs, verifying disk space, and testing system resources.

This error occurs when SQLite cannot access or open a database file. Common causes include incorrect file permissions, missing directories, invalid file paths, or insufficient disk space.

This error occurs when verifying a Firebase ID token that has been revoked due to account changes like password resets or explicit token revocation. Fix by forcing a token refresh or re-authenticating the user.

PostgreSQL does not allow window functions to be nested inside the arguments of other window functions. If you need to apply multiple window functions sequentially, use a CTE or subquery to compute the inner window function first, then reference that result in the outer window function.

This error occurs when the MongoDB driver's connection monitoring thread cannot maintain a stable connection to the server. The connection is closed before server selection can complete, typically due to network issues, authentication failures, or firewall restrictions.

This error occurs when attempting to attach a table as a partition to a partitioned table, but the existing data in that table violates the partition constraints or range bounds you are defining.

This error occurs in ioredis when a command cannot complete because the Redis connection has been lost and reconnection attempts have exceeded the configured limit. By default, ioredis will retry each pending command up to 20 times before failing with this error.

This error occurs when the XREADGROUP command is called without the required GROUP keyword and parameters. XREADGROUP is specifically designed for consumer group operations and mandates explicit group and consumer identification.

PostgreSQL Error 58P01 occurs when the server cannot locate a required file. This commonly happens with missing extension control files, incorrect file paths in COPY commands, or file permission issues. Fixing it requires verifying file paths, checking permissions, and restarting the database service.

Liquibase checksum validation fails when a previously executed changeset has been modified since it was first applied to the database. The stored checksum no longer matches the calculated checksum of the current changeset, triggering a validation error. Resolve this by accepting the new checksum, using validCheckSum tags, or clearing outdated checksums.

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.
