All Errors

This error occurs when Redis receives a malformed or invalid command. Common causes include incorrect command syntax, wrong number of arguments, or using a command unsupported in your Redis version. Verify your command syntax matches the Redis documentation.

This TypeScript error occurs when overriding a method in a subclass where the return type is not compatible with the base class method's return type. It's a type safety check that ensures method overrides maintain type compatibility, preventing runtime errors from incompatible return types. Understanding covariance and type compatibility rules resolves this object-oriented programming issue.

This TypeScript compiler error occurs when the type system encounters a union type with excessive combinations that exceed its internal complexity limits. The fix typically involves simplifying type structures, adding explicit type annotations, or refactoring complex type operations.

Prisma Accelerate cannot locate your project, typically due to an incorrect API key, disabled Accelerate project, or misconfigured connection string. This prevents query execution through Prisma's connection pooling service.

This error (code 28000) occurs when PostgreSQL denies access due to missing or incorrect authentication configuration in pg_hba.conf, invalid credentials, or authorization restrictions. Verify your connection credentials and pg_hba.conf settings to resolve it.

The "PGRST001: Connection to the database was lost" error occurs when PostgREST (Supabase's REST API layer) cannot maintain a connection to your PostgreSQL database. This typically happens due to network issues, database server problems, connection pool exhaustion, or infrastructure maintenance. The error returns HTTP status 503 (Service Unavailable) and indicates a temporary loss of database connectivity.

This error occurs when React Testing Library's waitFor utility times out while waiting for an element to appear in the DOM. The default timeout is 1000ms, and this error means the element didn't appear within that time. Common causes include async actions not being awaited, fake timers interfering, or elements not rendering as expected.

Prisma fails to establish a secure TLS/SSL connection to your database, typically due to misconfigured connection string parameters, certificate validation issues, or incompatible SSL settings between your client and database server.

This error occurs when you pass an invalid container type to React Testing Library queries or render functions. The container must be a valid DOM Element, Document, or DocumentFragment, but you're providing something else like null, undefined, a string, or an incorrect object type.

Firebase Analytics enforces a limit of 25 parameters per custom event. This error occurs when your app attempts to log an event with more than the allowed number of parameters, causing the event to be rejected by the Firebase Analytics service.

This warning indicates that more than the default 10 listeners have been added to an EventEmitter without being removed, potentially causing memory leaks. Node.js warns you to either remove unused listeners, use emitter.setMaxListeners() to increase the limit, or refactor to avoid accumulating listeners.

This TypeScript error occurs when you try to access a property on a value that TypeScript has narrowed to type 'never'. It typically happens with incomplete type guards, missing union cases, or exhaustive switch statements. The fix involves proper type narrowing and exhaustiveness checking.

This error occurs when using Redux Toolkit's createAsyncThunk function without providing the required type parameter. The type parameter is a string that identifies the thunk action and is used to generate Redux action type constants. The fix involves providing a unique string identifier as the first argument to createAsyncThunk.

A PostgreSQL function execution fails because the user lacks EXECUTE privilege. Grant the required permissions using GRANT EXECUTE to allow the user to call the function.

The PostgreSQL error "25005: no_active_sql_transaction_for_branch_transaction" occurs when attempting to create a branch transaction (using SAVEPOINT) without an active parent transaction. This happens when savepoint operations are executed outside of a transaction block or after a transaction has already been committed or rolled back.

The "over_sms_send_rate_limit: SMS send rate limit exceeded" error occurs when Supabase Auth blocks SMS sending due to rate limiting. This protection prevents SMS bombing attacks and excessive usage, typically triggered by too many authentication attempts to a single phone number within a short time period or exceeding overall project SMS quotas.

The "bad auth : authentication failed" error in MongoDB occurs when the database server rejects client authentication credentials. This typically happens due to incorrect username/password, missing authentication database, or misconfigured user permissions. The error indicates that MongoDB cannot verify the identity of the connecting client against its authentication system.

The UNAVAILABLE error in Firebase Cloud Messaging indicates that the FCM server is temporarily overloaded or under maintenance and cannot process your request at this time.

This error occurs when a user lacks the required privileges to access or modify a table. Fix it by granting appropriate permissions using the GRANT statement.

This error occurs in Redux Toolkit when using Immer incorrectly in reducers. It happens when you try to both mutate the draft state AND return a new value, which violates Immer's rules. The fix involves understanding how Immer works with Redux Toolkit's createReducer or createSlice.
