All Errors

PostgreSQL error 42710 occurs when attempting to create a database object (table, index, function, or sequence) that already exists with the same name in the same schema. This happens most commonly during migrations, deployments, or when running CREATE statements multiple times.

The PostgreSQL error "25007: schema_and_data_statement_mixing_not_supported" occurs when attempting to mix schema modification statements (DDL) with data manipulation statements (DML) in contexts where they cannot be combined. This typically happens in prepared statements, certain transaction blocks, or when using specific PostgreSQL extensions that have restrictions on statement mixing.

The Prisma P2030 error occurs when you try to use fulltext search queries without defining a fulltext index in your Prisma schema. This error is specific to MySQL databases and indicates that Prisma cannot find an appropriate fulltext index to execute your search query. The fix involves adding proper @@fulltext() attributes to your schema and ensuring your database supports fulltext indexing.

This MySQL client error occurs when a prepared statement is closed with mysql_stmt_close() while rows are still being fetched, immediately canceling the retrieval operation. The error is raised on the client side when the fetch loop is interrupted before all rows have been retrieved, typically due to premature statement cleanup in applications using the MySQL C API, PHP mysqli, Python mysql-connector, or similar language bindings.

Redis logs `ERR Module failed to load: Permission denied` when it cannot access a module file due to restrictive file permissions, SELinux/AppArmor restrictions, or incorrect ownership. The module fails to initialize, leaving Redis without the expected functionality until you adjust permissions, disable security modules, or relocate the module file. This guide covers the symptoms, root causes, and ordered steps needed to successfully load Redis modules.

The "validation_failed: Input validation failed" error occurs when data being inserted or updated in Supabase fails to meet database constraints, schema validation rules, or data type requirements. This error typically indicates issues with data format, missing required fields, or violations of database constraints like foreign keys, unique constraints, or check constraints.

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.
