All Errors

This error occurs when a JSON_VALUE() or jsonb_path_query() call in strict mode tries to extract a numeric value from a JSON path that doesn't contain a number or doesn't exist. Use ON ERROR/ON EMPTY clauses or switch to lax mode to handle missing numeric values.

The "connection refused because too many open connections" error occurs when MongoDB or its client drivers cannot establish new connections due to hitting connection limits. This typically happens in high-traffic applications, misconfigured connection pools, or when connections are not properly closed. The error prevents new database operations until connections are freed up.

PostgreSQL raises the duplicate function error (code 42723) when you try to CREATE a function with the same name and parameter types as an existing function. Use CREATE OR REPLACE FUNCTION to update existing functions or DROP the old one first.

This error occurs when a SQLite trigger uses the RAISE function to abort an operation, typically for data validation or business rule enforcement. The trigger detects invalid data and prevents the INSERT, UPDATE, or DELETE operation from completing. Common causes include validation triggers, audit trails, and complex business logic enforcement.

Supabase (PostgREST) returns PGRST102 when the JSON payload sent to a REST endpoint is malformed, contains syntax errors, or violates schema constraints. This error prevents the request from reaching the database and requires fixing the JSON structure before resubmitting.

PostgreSQL error 3D000 means you specified a database name that doesn't exist or is misspelled. Fix it by verifying the database name exists and checking your connection string.

This error occurs when attempting to drop a PostgreSQL role that still has privileges granted on database objects. PostgreSQL prevents the role from being dropped to maintain security and ownership integrity.

The Prisma P5004 error occurs when you attempt to use a feature that is not yet supported in Prisma Accelerate. This typically happens when trying to use advanced database operations, specific query patterns, or newer Prisma features that haven't been implemented in the Accelerate service yet. The fix involves identifying the unsupported feature and using alternative approaches or waiting for Accelerate to support it.

This PostgreSQL error occurs when there's a conflict with escape characters in string literals, typically in COPY commands, E'...' strings, or when using backslashes as escape characters. The parser encounters ambiguous or conflicting escape sequences that it cannot resolve.

PostgreSQL raises error 38001 when SQL statements are attempted in contexts where they are explicitly prohibited, typically for security reasons. This occurs in security-definer functions, certain procedural language handlers, or when attempting to execute SQL in contexts that could bypass security controls.

The "$out must be the last stage in the pipeline" error occurs when you try to use the $out aggregation stage anywhere except as the final stage in a MongoDB aggregation pipeline. The $out stage writes pipeline results to a collection and must be the last operation. This error prevents pipeline execution and requires reordering stages to place $out at the end.

PostgreSQL throws "Invalid schema name" (error 3F000) when referencing a non-existent schema, using reserved names starting with pg_, or due to case sensitivity issues. Verify the schema exists, check naming rules, and use correct casing.

This error occurs when one or more files in your apt sources directory contain syntax errors or malformed entries. Identifying and fixing the problematic source file restores apt functionality.

The "Prepared statement does not exist" error occurs when using connection poolers like PgBouncer or PgPool, where prepared statements are lost between transactions or connections. This can be fixed by disabling prepared statements, using binary parameters, or connecting directly to the database.

MySQL throws ER_WINDOW_INVALID_WINDOW_FUNC_USE when a window function is used incorrectly, such as mixing aggregate and non-aggregate window functions improperly, using window functions in invalid contexts like WHERE clauses, or violating MySQL's specific window function syntax rules. This error indicates a fundamental misunderstanding of how window functions work in MySQL.

PostgreSQL error 42883 occurs when a function call cannot be matched to any defined function with matching name and argument types. Common causes include typos, incorrect argument types, missing extensions, or schema path issues.

This error occurs when Elasticsearch's circuit breaker mechanism prevents a request from executing because it would exceed memory limits. Circuit breakers protect the cluster from out-of-memory errors by monitoring memory usage and rejecting requests that would push the system beyond configured thresholds.

The "Triggered action exception" error occurs when a database trigger raises an explicit exception or fails during execution. This error aborts the SQL operation that fired the trigger and rolls back the entire transaction, indicating either a logic error in the trigger function or data that violates trigger-defined constraints.

This Firebase Cloud Messaging error occurs when Firebase cannot authenticate with Apple Push Notification service (APNs) using the provided certificate or with web push services using the provided auth key. The error indicates authentication failures with third-party push notification services that Firebase relies on for message delivery.

The TransactionTooLarge error in MongoDB occurs when the total size of all operations within a single transaction exceeds the 16MB limit (16,793,600 bytes). This limit applies to the combined size of all documents being inserted, updated, or deleted within a transaction, including their BSON representation overhead. The error prevents transaction execution and requires breaking large operations into smaller batches or optimizing document size.
