Generic Exception Thrown (ARCH3167)

Key typescript.logging.throw-generic-error · Severity info · Category logging

Throwing the base Error type instead of a specific domain exception forces callers into broad catch blocks. They cannot discriminate by error type.

Incorrect

function withdraw(account: Account, amount: number) {
  if (amount > account.balance) {
    throw new Error("insufficient funds");
  }
  account.balance -= amount;
}

Correct

class InsufficientFundsError extends Error {}

function withdraw(account: Account, amount: number) {
  if (amount > account.balance) {
    throw new InsufficientFundsError("insufficient funds");
  }
  account.balance -= amount;
}

Fix

Throw a specific domain exception that callers can catch selectively instead of base Error.
