All Errors

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.

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.

Supabase returns 'invite_not_found: Invite has expired or already been used' when a user attempts to accept an email invitation that is no longer valid. This occurs when the invitation token has expired (default 24-48 hours), has already been redeemed, or was manually revoked. The fix involves resending a fresh invitation, extending the token expiry, or checking for duplicate acceptances.

This error occurs when your application tries to write to a Redis read-only replica instead of the primary master node. Redis replicas are intentionally set to read-only by default to prevent accidental writes and data inconsistency.

The "VersionError: No matching document found for id" error in MongoDB occurs when using optimistic concurrency control with document versioning. This typically happens when trying to save a document that has been modified or deleted by another process since it was loaded. The error indicates a version mismatch between the document in memory and the document in the database.

MongoDB aborts a transaction that runs longer than the server parameter `transactionLifetimeLimitSeconds` (60 seconds by default). This error shows up when a transaction spends too much time inside the session, usually because of large workloads, missing indexes, or waiting on long-running operations.

Supabase surfaces PostgREST’s PGRST107 code whenever it cannot decode or verify the bearer JWT, so the request is rejected before any policies or SQL run. This article walks through inspecting the Authorization header, checking the JWKS/signing key configuration, and refreshing tokens after key rotation.

This MySQL connection error occurs when a client application cannot establish a local socket connection to the MySQL server. The error typically indicates that the MySQL server is not running, the socket file path is incorrect, or there are permission issues preventing access to the socket file. Local socket connections are commonly used for connections from applications running on the same server as the database.

This error occurs during Supabase authentication when the code_verifier stored from the initial PKCE request doesn't match the one sent during token exchange. It typically indicates the code verifier wasn't persisted correctly, or the authentication request was completed on a different browser/device than where it started.

This PostgreSQL error occurs when invalid arguments are passed to the SUBSTRING() function, which extracts parts of strings. The error typically happens when start positions or lengths are out of bounds, negative, or incompatible with the input string data type.

This error occurs when attempting to create a replication origin with a name that already exists in the pg_replication_origin catalog, typically during logical replication setup or when manually creating origins.

This Prisma error occurs when you try to disconnect a relation that doesn't exist or is already null, or when trying to connect records that don't exist in the database. It happens when foreign key constraints fail because related records are missing.
