Rethrow Loses Stack Trace (ARCH3154)

Key typescript.logging.rethrow-without-cause · Severity warning · Category logging

Throwing a new error inside a handler without passing the original exception as cause discards the root cause and stack trace. The debugging context is erased entirely.

Incorrect

async function fetchOrder(id: string): Promise<Order> {
  try {
    return await api.get(`/orders/${id}`);
  } catch (err) {
    throw new Error("failed to fetch order");
  }
}

Correct

async function fetchOrder(id: string): Promise<Order> {
  try {
    return await api.get(`/orders/${id}`);
  } catch (err) {
    throw new Error("failed to fetch order", { cause: err });
  }
}

Fix

Pass the original exception via the cause option when throwing the new error.
