All Errors

This Foreign Data Wrapper error occurs when a column attribute number referenced in an FDW operation is invalid or out of range, typically after altering table structure without updating foreign table definitions.

The "PGRST000: Could not connect to the database" error occurs when PostgREST (Supabase's REST API layer) cannot establish an initial connection to your PostgreSQL database. This typically happens due to database being paused, incorrect credentials, configuration issues, or infrastructure problems. The error indicates that the database service is unreachable or misconfigured.

This error occurs when using Firebase Authentication's ActionCodeSettings with Android-specific options like installIfNotAvailable or minimumVersion without providing the required androidPackageName parameter.

This error occurs when PostgreSQL cannot find a table, view, or other relation with the specified name. The most common causes are case sensitivity issues, schema mismatches, table not being created, or incorrect connection to the database. Verify the table exists, check exact naming and case sensitivity, specify the correct schema, and ensure you're querying the right database.

This error occurs when the MySQL client and server fail to complete the initial handshake process during connection establishment. It typically indicates authentication protocol mismatches, version incompatibility, or network configuration issues.

PAM (Pluggable Authentication Modules) authentication fails during SSH login. This typically means the authentication module rejected the credentials or user account. Common causes include incorrect passwords, disabled user accounts, invalid PAM configuration, or SSH/PAM incompatibilities after system updates.

This error occurs when the pg_dump client tool version is older than the PostgreSQL server you're backing up. PostgreSQL requires pg_dump to be the same version or newer than the target server.

This error occurs when trying to use a WITH HOLD cursor in a transaction with a different isolation level than the one that created it. The cursor must maintain the same isolation level throughout its lifetime.

This Mongoose error occurs when trying to register a model with the same name multiple times. It commonly happens in development environments with hot-reloading, serverless functions, or test suites that re-import model files.

This SSH error indicates the server closed the connection before authentication completed. Common causes include too many failed login attempts, authentication method mismatches, or failed brute-force attacks.

MySQL ERROR 2006 "server has gone away" occurs when the database connection is lost or closed unexpectedly. This happens when idle connections exceed the timeout threshold (default 8 hours), the server is restarted, packets are too large, or network issues disconnect the client. The error indicates the connection was valid but is no longer available.

ERROR 1206 occurs when InnoDB exhausts the lock table buffer space during large transactions or high-concurrency operations. The primary fix is increasing innodb_buffer_pool_size, though breaking large operations into smaller batches provides a quick workaround.

This error occurs when two or more modules require each other, creating a dependency loop. Node.js returns an incomplete module export to prevent infinite loops, resulting in undefined imports and runtime errors.

This error occurs when attempting to register multiple PerformanceObserver instances for the same entry type in Node.js. Only one observer can monitor a specific entry type at a time, and duplicate registrations trigger an assertion failure that can crash the process.

Node.js shows a deprecation warning when code uses the built-in punycode module. This module has been deprecated since Node.js v7 and became a runtime deprecation in v21, warning that it will be removed in a future major version.

This error occurs in Node.js cluster mode when a worker process fails to exit within the expected timeout period after disconnect() is called. It typically indicates that the worker has open connections or pending operations preventing graceful shutdown.

This error occurs when a Transform stream's _flush() method encounters an error during stream finalization. The flush method is called after all data has been processed but before the stream ends, and errors here indicate failed cleanup operations or final transformations.

This error occurs when the Content-Length header value does not match the actual size of the response body received. It typically happens when the server sends an incorrect header, a proxy modifies the response without updating headers, or compression is applied inconsistently.

This error occurs when a web application tries to make a cross-origin HTTP request, but the server does not allow requests from the requesting origin. Browsers enforce CORS (Cross-Origin Resource Sharing) to protect users from potentially malicious cross-origin requests.

This SSH warning appears when the host key for a remote server doesn't match the stored fingerprint in your known_hosts file, which can indicate DNS spoofing, server changes, or IP address reuse. Usually this is benign but requires verification.
