All Errors

The PostgreSQL error "39P03: event_trigger_protocol_violated" occurs when an event trigger function violates the expected protocol for event trigger execution. Event triggers are special triggers that respond to DDL (Data Definition Language) events like CREATE, ALTER, or DROP commands, and they must follow specific interface requirements.

This error occurs when a Redis command receives an incorrect number of arguments. Each Redis command has specific argument requirements, and supplying too few or too many arguments triggers this validation error.

Prisma P2005 occurs when data in your database doesn't match the type defined in your Prisma schema. This type mismatch prevents Prisma from reading or updating records. Fix it by aligning your database values with your schema definition or adjusting your schema to match the actual data.

Redis Cluster returns -ASK redirects when a hash slot is being migrated between nodes. This is a normal part of cluster rebalancing and requires clients to acknowledge the temporary migration state before retrying commands.

PostgreSQL throws this error when a query uses the same alias name for multiple columns, table joins, or expressions. Fix it by ensuring each alias is unique within the query scope.

This error occurs when a database query through Prisma Pulse fails to return a response within the configured query timeout limit. Common causes include slow queries, insufficient database connections during high traffic, or database resource contention.

The Prisma P2015 error occurs when Prisma cannot find a related record during a create or update operation. This typically happens when you try to connect a record to a non-existent foreign key reference, such as linking a post to a user that doesn't exist. The fix involves verifying your relation data and ensuring referenced records exist.

Supabase throws `signup_disabled: Signups are disabled` when the project explicitly refuses to create new accounts, so every signUp, OAuth, or OTP request returns a 400. Re-enable the "Allow new users to sign up" toggle or clear the same flag in self-hosted deployments to allow account creation again.

This PostgreSQL error occurs when you attempt to create a prepared statement with a name that already exists in the current session. The solution is to deallocate the previous statement or use a different name.

This DNS lookup error occurs when your system cannot resolve MongoDB Atlas SRV records, typically due to DNS server limitations or network configuration issues preventing mongodb+srv:// connections.

This error occurs when attempting to drop or rename a column that is referenced by a CHECK constraint. MySQL prevents the operation to maintain constraint integrity unless the constraint is dropped first.

Supabase (PostgREST) rejects any POST/PATCH/PUT request that transports a body without so much as a Content-Type header. The 405/PGRST101 response is PostgREST telling you it has no idea how to deserialize the payload, so the mutation never reaches the database. Setting the right media type fixes the error instantly.

Firebase Storage throws this error when you subscribe to upload task updates with an unsupported event label. The SDK only recognizes the built-in state listeners that report running, paused, or progress updates, so any other event string triggers the invalid-event-name payload.

Firebase rejects continue URLs that point to domains outside Authentication → Settings → Authorized Domains, so email-action or redirect flows fail with auth/unauthorized-continue-uri. Whitelist the domain and make sure ActionCodeSettings.url uses that host before sending links.

PostgreSQL raises this error whenever an external routine (C extension, FDW, or PL handler) signals a problem with a malformed SQLSTATE. The server enforces the SQLSTATE rules documented in the error-code appendix so that clients receive a predictable error protocol.

The Firebase Admin SDK enforces session cookies to last between five minutes and two weeks, so creating a session cookie with a shorter or longer duration fails with this error and prevents the login endpoint from issuing authenticated cookies.

This error occurs when using PostgreSQL's JSON_VALUE function with a JSON path expression that returns an array or object instead of a scalar value. The JSON_VALUE function is designed to extract single scalar values, and will fail if the path expression points to a non-scalar result.

The Spark (free) Firebase plan caps Firestore at 50,000 document reads per 24-hour window, so once your project consumes the allotment Firestore returns a ResourceExhausted error and blocks any further reads until the quota resets. Confirm the quota usage, upgrade to Blaze, and cut the number of reads (caching, aggregation, alerts, etc.) so you no longer burn through the free limit.

This error occurs when a Docker Swarm cluster loses quorum because too few manager nodes are available. The Raft consensus algorithm requires a majority of managers to be online to elect a leader. Recovery typically involves reinitializing the swarm with --force-new-cluster on a surviving manager.

Firebase Cloud Messaging throws this error when too many notifications hit the same token or topic inside FCM’s per-target quota window. Spread the burst over five minutes or request a temporary quota bump before retrying.
