All Errors

This error occurs when PostgreSQL cannot find a custom type referenced in a function, procedure, or variable declaration. Common causes include missing schema qualification of custom types, incomplete migrations, enum type naming mismatches, or using non-PostgreSQL-compatible types like STRING instead of TEXT.

The PostgreSQL error 55006 (object_in_use) occurs when you attempt to drop or modify a database object that is currently being accessed by another session. Terminate conflicting connections or wait for the object to become available.

This error occurs when PostgreSQL is in recovery mode (e.g., on a Hot Standby replica), which restricts write operations. The database must either complete recovery or be promoted to primary mode to execute write commands.

This error occurs when you attempt to insert or update a row with a value that already exists in a column marked as UNIQUE. SQLite enforces uniqueness constraints and rejects duplicate values, preventing data inconsistency in your database.

The FAILED_PRECONDITION error occurs when a Firestore operation fails because necessary preconditions (like composite indexes or transaction constraints) are not met. Most commonly caused by missing indexes on compound queries combining where() and orderBy().

A deadlock occurs when two or more transactions wait for each other to release locks, creating a circular dependency. PostgreSQL automatically detects and terminates one transaction to break the deadlock. Fix it by ensuring transactions always access rows in a consistent order.

This error occurs when a user with multi-factor authentication (MFA) enabled tries to sign in. Firebase requires completing the second factor challenge before granting access. Handle this error by catching it and using the MultiFactorResolver to prompt the user for their second factor.

This error occurs when your Firestore security rules deny access to the requested resource. Fix it by reviewing and updating your security rules to allow authenticated users or by ensuring the user is properly logged in before accessing the database.

This error occurs when you try to create or update a record with a foreign key value that doesn't match any primary key in the referenced table. Verify the referenced record exists and check for data type mismatches between your schema and database.

PostgreSQL runs out of shared memory when the lock table exceeds capacity, typically due to excessive table locking or high concurrency. Increase max_locks_per_transaction or adjust connection settings to resolve.

The functions/permission-denied error occurs when your Cloud Function lacks IAM permissions to access other Firebase services. This is typically caused by missing or insufficient Cloud IAM roles assigned to the service account running your function.

PostgreSQL enforces a hard limit of 1,600 columns per table. This error occurs when you exceed that limit or hit the 1,664-column tuple limit in SELECT statements. Redesign your schema using arrays, JSON, or table partitioning.

The DEADLINE_EXCEEDED error occurs when a Firestore operation exceeds the default 60-second timeout window. This commonly happens with large batch operations, complex queries, or high-volume read/write operations. Fix it by optimizing queries, breaking operations into smaller chunks, and addressing latency issues.

PostgreSQL raises error 54000 when a query or schema surpasses built-in limits such as maximum columns per table, index key size, or expression nesting depth. Resolve by restructuring your schema, simplifying queries, or breaking down large operations.

This error occurs when a user tries to create an account with an email that already exists in your Firebase project. Learn how to detect this error, prompt users to log in instead, and check for existing accounts before sign-up.

Stack depth limit exceeded errors occur when PostgreSQL query execution exceeds the maximum call stack depth. This typically happens with recursive triggers, large IN clauses, or deeply nested queries. The fix depends on the root cause and may involve restructuring queries, preventing trigger recursion, or adjusting configuration parameters.

PostgreSQL error 3B000 indicates a general savepoint exception, typically occurring when attempting to rollback or release a savepoint that no longer exists. This commonly happens in ORMs when transaction state becomes desynchronized.

PostgreSQL raises error 54001 when a query exceeds internal planning complexity limits due to excessive joins, nested subqueries, or deeply nested expressions. Break the query into smaller parts using temporary tables or CTEs to resolve this.

The auth/wrong-password error occurs when a user attempts to sign in with an incorrect password for their Firebase account. This common authentication error prevents login and can be resolved by implementing proper error handling, password reset functionality, and validating user input.

Error 2061 occurs when the MySQL server selects an authentication plugin (usually caching_sha2_password in MySQL 8.0+) that the client cannot properly execute. Fix by using SSL/TLS, requesting the RSA public key, or changing the authentication plugin.
