All Errors

Firebase Cloud Functions exceed their timeout limit when operations take longer than allowed (60 seconds for HTTP functions, 540 for background). Resolve by increasing timeout, optimizing code, or breaking large operations into smaller batches.

When dropping a PostgreSQL database fails or was completed unexpectedly, it usually means the database is still in use or recovery incomplete. Learn how to safely drop databases and recover from failed drop operations.

Redis Cluster stops accepting queries when hash slots are not assigned to nodes. This error indicates the cluster is in a partially degraded state where one or more of the 16384 hash slots lack node coverage, preventing normal operations.

A query exceeded the allowed execution time. Configure statement_timeout, optimize slow queries with indexes, monitor lock contention, and adjust timeout settings based on query complexity.

PostgreSQL intentionally refuses to run as the root user for security reasons. Switch to an unprivileged user (typically postgres) to start the database server successfully.

Redis rejected your authentication credentials. This occurs when you provide an incorrect password, wrong username, or use an invalid credential format when connecting to a Redis instance with ACL (Access Control List) authentication enabled.

Window functions like ROW_NUMBER(), RANK(), and DENSE_RANK() cannot be used directly in WHERE clauses because they are evaluated after the WHERE clause filters are processed. This limitation exists due to SQL's logical order of operations. Use a CTE (Common Table Expression) or subquery to compute window functions first, then filter in the outer query.

PostgreSQL rejects configuration parameters with unrecognized or unsupported values during startup or connection. This typically affects locale, timezone, or text search settings.

Your AWS RDS PostgreSQL instance has exhausted its allocated storage capacity. Resolve this by increasing storage, enabling autoscaling, or removing unnecessary data. Immediate action is required to prevent database unavailability.

PostgreSQL error 57014 occurs when a query exceeds the configured statement_timeout limit and is automatically terminated. This protects the server from runaway queries. Increase the timeout, optimize the query, or check for locks causing delays.

PostgreSQL config file errors occur when there are syntax mistakes or invalid parameters in postgresql.conf. These prevent the server from starting and can be fixed by reviewing log messages and validating configuration syntax.

The "malformed array literal" error in PostgreSQL occurs when array values are provided in incorrect syntax. PostgreSQL requires arrays to be enclosed in curly braces with proper comma separation and quoted elements. Common causes include using JSON syntax instead of PostgreSQL syntax, missing quotes around special characters, and data type mismatches. Fixing requires proper array formatting according to PostgreSQL conventions.

Firebase Cloud Functions throws an internal error when your function encounters an unhandled exception, timeout, permission issue, or returns invalid data. This generic error typically indicates a problem in your function code that needs debugging via console logs.

PostgreSQL idle session timeouts terminate inactive database connections to prevent lock accumulation and table bloat. Learn how to configure and troubleshoot idle_session_timeout and idle_in_transaction_session_timeout parameters.

A protocol mismatch occurs when your MySQL client cannot communicate with the server due to incompatible protocol versions. This typically happens after version upgrades, downgrades, or when connecting to the wrong port.

This error occurs when you try to TRUNCATE a table that is referenced by another table through a foreign key constraint. TRUNCATE is much faster than DELETE but cannot proceed if child tables have references. Use CASCADE to truncate all related tables together, truncate tables in dependency order, or temporarily disable constraints.

PostgreSQL error 57P03 occurs when the server cannot accept connections because it is starting up, shutting down, or in recovery mode. This is typically temporary and resolves once the server completes its startup or recovery process.

This error occurs when your parameterized SQL query references a placeholder like $1 or $2, but the corresponding parameter value was not provided when executing the statement. This is typically a binding mismatch between your application code and the prepared statement.

When a query fails in a PostgreSQL transaction, all subsequent commands are rejected until the transaction is rolled back. This occurs by design to maintain data consistency and requires explicit recovery using ROLLBACK or SAVEPOINT.

This error occurs when email authentication is disabled in Supabase Auth settings, preventing new users from signing up with email/password. Enable email provider in your project dashboard to allow email-based signups.
