All Errors

Error 42704 occurs when a query references a table, column, type, or other database object that does not exist. This commonly happens due to typos, case sensitivity issues, or missing schema qualifiers.

TransientTransactionError occurs when MongoDB transactions fail due to temporary conditions like network issues, replica set elections, or resource constraints. This error indicates the transaction can be retried safely. Understanding when and how to retry transactions is key to handling this error.

PostgreSQL error 42P02 occurs when a prepared statement references a parameter placeholder like $1 but no actual value is supplied. Fix by providing all bind variables or removing unused placeholders.

DynamoDB returns ItemCollectionSizeLimitExceededException when a local secondary index (LSI) or table partition exceeds the 10 GB size limit for item collections. This occurs when too much data accumulates under a single partition key value, requiring data redistribution or archival strategies.

PostgreSQL error 42P01 occurs when a query references a table that does not exist. This commonly happens due to misspelled table names, schema confusion, case sensitivity issues, or connecting to the wrong database.

Supabase returns "flow_state_not_found: PKCE flow state could not be found" when the OAuth authorization flow state is missing, expired, or corrupted. This typically happens when users take too long to complete social login, when browser sessions are cleared mid-flow, or when PKCE code verifiers don't match. The fix involves adjusting flow timeouts, preserving session storage, and ensuring consistent PKCE implementation.

PostgreSQL error 42703 occurs when a query references a column that doesn't exist in the table. This is usually caused by typos, case sensitivity issues, or schema changes.

This error occurs when Elasticsearch operations exceed their configured timeout limits, causing tasks to be cancelled. Common causes include slow queries, resource contention, network issues, or insufficient cluster resources. The timeout prevents operations from hanging indefinitely but requires tuning timeouts or optimizing queries.

The "Ambiguous parameter" error occurs when PostgreSQL cannot determine which parameter or column you are referencing because the same name appears in multiple contexts. This happens when parameters have conflicting type expectations or when variables share names with table columns in functions.

The Prisma P2016 error occurs when the query engine cannot interpret your database query due to ambiguity or invalid structure. This error prevents query execution and requires fixing the query syntax or structure.

PostgreSQL throws an ambiguous column error when a column name exists in multiple tables without proper qualification. Qualify column names with table aliases or names in JOIN queries to resolve the error.

PostgreSQL raises a duplicate schema error when you try to create a schema that already exists. Use CREATE SCHEMA IF NOT EXISTS or check if the schema is already present before creating it.

Redis Sentinel logs "+try-failover: New failover in progress" when multiple failover attempts overlap, usually because a previous failover is still underway or quorum cannot be reached. This prevents duplicate promotions and ensures only one master election occurs at a time. To resolve, wait for the current failover to complete, verify Sentinel quorum and network connectivity, then retry if needed.

The Prisma P5000 error occurs when Prisma Accelerate cannot parse or understand a request from your application. This typically happens due to malformed query syntax, incompatible Prisma Client versions, or network issues corrupting the request payload. The fix involves checking your query structure, verifying Prisma Client compatibility, and ensuring network stability.

The "duplicate table" error (SQLSTATE 42P07) occurs when you attempt to create a table that already exists in the database. Use CREATE TABLE IF NOT EXISTS to prevent this error.

Redis Cluster returns `CROSSSLOT Keys in request don't hash to the same slot` when you attempt a multi-key operation (like MGET, MSET, or sharded Pub/Sub) on keys that hash to different hash slots. Redis Cluster partitions data across 16384 slots, and multi-key commands require all keys to map to the same slot unless you use hash tags. This guide explains slot hashing, hash tags, and how to structure keys or use client-side routing to avoid cross-slot errors.

This MySQL error occurs when a configuration file has overly permissive file permissions that allow other users to read or write to it. MySQL enforces strict security by requiring config files to be readable/writable only by the current user.

PostgreSQL error 42804 occurs when trying to assign or compare values of incompatible data types. This requires explicit type casting using the :: operator or CAST() function to resolve the mismatch between columns and values.

The Prisma P2023 error indicates a data type mismatch between your database and what Prisma expects based on your schema. This typically occurs due to integer overflow, invalid data types, failed conversions, or schema mismatches. The fix usually involves validating data types, migrating column types, or ensuring your schema matches your actual database structure.

DynamoDB returns ImportNotFoundException when you try to access or describe an import job that does not exist, has been deleted, or is in a different region. This error occurs with import operations like importing data from S3 into DynamoDB tables when referencing imports by their Amazon Resource Name (ARN) or import ID.
